Power Windows Not Working? (10 Common Causes and How to Fix)

  • Window Lock Button is On.
  • Bad Window Regulators.
  • Bad Fuse.
  • Bad Window Motor.
  • Snow and Ice.
  • Torn, Loose, or Dirty Window Gasket.
  • Bad Power Window Switch.
  • Wiring Issues.

What causes car windows to stop working?

Window malfunctions are typically caused by a faulty window regulator (also called a window track), or a broken motor, cable pulley or window switch. Overheated motors often cause intermittent problems, Benet says. When the motor – located inside the door – cools down, it may start working again.

How do I know if my window regulator or motor is bad?

Here are some of the symptoms to look out for:

  1. Grinding or Clicking Noises While Rolling Up the Window. The window regulator, or motor, is located in the door of your car.
  2. Window Won’t Stay Rolled Up or is Off-Center.
  3. The Button Doesn’t Work the First Time.
  4. Window Seems Sluggish or Too Quick.
  5. How We Can Help.

How can you tell if a window fuse is blown?

Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.

Can a fuse stop a window from working?

A blown fuse is a common cause of a window being stuck. This does not mean that all electronics in your vehicle will stop working, as most modern cars will have many fuses—one might cover audio and speaker systems, another might control windows and lights. This problem can be fixed quickly by replacing the fuse.

How can you tell if a window switch is bad?

To test the window switch you will need to use a voltmeter and ohmmeter.

  1. Remove the faulty window switch from the door.
  2. Turn the switch to the “open” position.
  3. Attach the voltmeter to the switch plug and test to see if there are 12 volts coming from terminal 4 to the ground and from terminal 5 to the ground.

Does each power window have its own fuse?

Check the fuse Other cars have individual fuses for each window motor so failure will only affect the one window. In some cars the fuse is in the main fusebox but many makers use in-line fuses so check with your manual to find where the fuse is and replace it if blown. Then test the window.

How much does it cost to fix a car window?

Typical costs: Replacing the glass for a standard passenger or driver side car window costs $100-$350, depending on the model of vehicle. Windows for rare or exotic vehicles can cost more. Users report paying $70-180 to replace a standard side car window.

Why does my window go down but not up?

It might be as simple as a fuse or as complicated as the mechanism jammed and burned out the motor. If a window goes down but not up it is usually a bad switch. In that case you replace the switch. If you are a real redneck you might try taking the switch apart and cleaning the contacts.

What does a bad window regulator sound like?

If the window is able to move and you hear strange noises, this could be an early warning sign of a failing regulator. The noises may sound like grinding, clicking, or chattering.

What happens when window regulator goes bad?

A broken window regulator cable can cause the window to jam or fall down inside the door. If this happens, in some cars, the window can be re-secured without replacing parts, in others the window regulator might need to be replaced. A car is considered unsafe when power windows don’t function properly.

How much is a fuse for a car window?

The cost to have a fuse replaced depends on the style of fuse used in the make and model, and the power requirement. Most common fuses are only $10 to $20, although some specialty fuses are more than $100 to replace, in addition to diagnostic costs.

Where is the fuse for car windows?

Changing a Fuse. Locate and open the fuse box. It should be located inside the car as a part of, or near, the dash. Check your owner’s manual to locate that operates the windows.

How to Fix Power Windows

Power windows that are not working properly are a big pain, especially when they become stuck down in extreme heat or cold. Following these methods will allow you to troubleshoot and repair your power windows in a few of hours. Another tollbooth, another mile-or, at least, it appears as though tollbooths come every mile on this road, with a half mile of traffic idling its slow way up to the token monster-and another tollbooth, another mile-and another tollbooth, another mile. You’re within an arm’s reach of the bin, so you use one hand to flick the power window switch while the other fingers a token, ready to toss it into the basket as soon as you depress the accelerator.

Power windows, on the other hand, are often one of the most dependable technologies in a late-model automobile.

What’s going on?

There is a straightforward regulator mechanism, which is often comparable to the mechanism found in garden-variety hand-cranked windows.

  • The process of troubleshooting is rather basic once you’ve removed the door panels.
  • First and foremost, are all of the windows malfunctioning?
  • As a first step, check the fuse box to see if it is blown or if the windows can’t be moved.
  • A few sticky window channels and the passage of time might cause a fuse to blow.
  • If the fuse is blown, pressing the window button will have no effect at all: the motor will not moan and the glass will not tremble when you press the button.
  • If this is the case, the fuse should be checked.

You don’t want to be yanking fuses all over the place looking for a blown one because you might interrupt power to the engine management computer, resulting in poor driving performance for about 30 minutes, or you might accidentally reset all of the buttons on your car radio to that underwater alien rock and gospel station.

  1. Is it possible that all of the windows are closed?
  2. It’s possible that you’ll have the chance to go spelunking inside the door even if it’s only one person.
  3. If you’ve reduced the problem down to an electrical issue that isn’t as straightforward as a blown fuse, you’ll need to gather a schematic of your car’s electrical system as well as a voltmeter or 12v test light at this point.
  4. You’ll probably find a loose or corroded connector that’s causing the electricity to the motor to be interrupted somewhere.
  5. If the driver’s door switch does not open the right rear door, but the switch in the door does, search for a faulty switch in the driver’s door or a defect in the wiring that connects the driver’s door to the right rear door.
  6. Sesame Street is now open.
  7. It may be possible to pry the panel up with your fingers and backprobe the connections on some automobiles, such as the one seen in our leading picture.

The fasteners that hold door panels in place are a dizzying array of different types.

The perimeter of the panel is often kept in place by delicate plastic studs that are only intended to be used once.

After you’ve removed the door panel, gently remove the weather sheeting from the opening.

Caution: You now have the capacity to insert your fingers into areas that they would ordinarily not be able to reach.

Proof of Possibility Test if the motor comes to life by connecting a jumper wire directly from the battery’s positive terminal to the motor’s positive terminal as absolute confirmation that the problem is electrical.

Take a look at the schematic.

If just the rears are acting up, look for a faulty switch.

You’ll have to get another one.

Loose fasteners can produce severe misalignment, which can cause gear-type regulators to become jammed.

It is necessary to inspect the gaskets if the window has a slow spot, is difficult to open or close correctly.

If the gasket is loose or even ripped, you may be able to fix it with a little effort.

Remove the old adhesive with lacquer thinner and reinstall the gasket into its original position.

If the gasket is damaged, you may be able to simply fix the tear with super glue if the tear is small enough.

If you are replacing the gasket on the section of it that sits outside the glass, you should exercise caution since it may allow rain and salt spray to seep into the door in amounts that are too great for the door’s internal drainage system to cope with.

If it is not immediately apparent that the gasket is faulty, thoroughly check the whole gasket and channel.

Lacquer thinner should be used to clean the gasket and window surfaces to eliminate oxidized rubber and scum buildup.

In almost all cases, misalignment will result in a significant increase in friction, to the point where the motor’s torque is no longer sufficient to move the glass adequately.

It’s also conceivable that the issue is located deeper within the door frame.

Remember to pull the fuse in order to avoid having your fingers amputated.

In other cases, the problem is as simple as a loosened bolt that allows the door’s inner structure to move about, causing the window track to become misaligned.

If the door has been damaged in a collision, there are no more bets.

Finally, it is possible that the mechanism that raises and lowers the window is malfunctioning.

Keep your fingers away from the controls once more.

In some cases, cables might become tangled in the drum or become sticky.

Remember that there are gaskets in the window track below the top of the door that you may need to reglue, replace, or lubricate if the window track is damaged.

Depending on the situation, it may be feasible to replace just the motor or the complete mechanism. Check the weatherstripping and window channel for ripped, loose, or folded rubber pieces, as well as any foreign items that may have gotten caught in the system.

HOW IT WORKS: Automatic Windows

Some late-model high-end vehicles are equipped with frameless windows that automatically crank themselves open by a quarter-inch or so as the doors are opened and closed. It occurs at such a rapid pace that you may not even realize it. The window opens quickly, allowing the seal to be broken before the door latch is released. When the door latch locks, it automatically closes approximately a second after it latches. There are two distinct advantages to doing so. In the first place, a slightly open window allows for the ventilation of internal air, which can actually make it difficult to open doors in securely sealed automobiles by forcing the door open against the force of air pressure.

  1. It is possible that the seal will seem more like that of a sedan door seal, with a little lip projecting over top of the window glass.
  2. This sort of seal provides for less infiltration of water and noise.
  3. Repairs will almost certainly necessitate the use of a manufacturer shop manual as well as the purchase of pricey replacement components.

10 Causes of Power Windows Not Working in a Car (w/ Simple Fixes)

(This page was last updated on September 10, 2021.) The era of autos with hand-crank windows has come to an end. Power windows are now standard equipment in virtually every new car manufactured today, and they require electrical power to operate effectively. Power windows are extremely handy to use since they can be opened and closed with the touch of a button on your door. You won’t have to deal with the inconvenience of turning a crank handle with your hand. Power windows, on the other hand, have one significant drawback.

Because of the internal mechanism, it is not possible to force the window open or closed.

Fortunately, the ability of a window to open and close is typically not a safety concern and does not have an impact on driving performance.

If your windows stop operating, try some troubleshooting to see if you can figure out what’s wrong with them. Power windows may need to be repaired or replaced by a local technician or dealership, depending on the circumstances. View this page for more information:Easiest Way to Remove Window Tint

Common Causes of Power Windows Not Working

There are a variety of reasons why your car’s windows may cease to function properly. The problem is more likely to be electrical than mechanical if you do not hear or see any movement when you press the button while it is activated. Here are some of the probable difficulties to look out for in the event that this occurs to you.

1) Window Lock Button is On

If the lock-out button on the driver’s door has been pressed, the most straightforward and obvious (but easily overlooked) problem is that the door has been locked. Until the button is pressed again, a safety function disables the switches for all other windows in the car, preventing them from being used.

2) Bad Window Regulators

A window regulator is the device that is responsible for raising and lowering a power window. Each automobile door that has a power window is equipped with a window regulator that allows the window to be moved. It is connected to a power window motor by means of wires. If the regulator fails, pressing the up or down buttons will have no effect on the movement of the window. It is possible that the crank gears are worn or damaged, or that the regulator is out of alignment. It will be necessary for you to have the window regulator repaired or replaced.

3) Bad Fuse

If all four windows are stuck and will not move, it is probable that the fuse for the window regulators is the source of the issue. When you push any of the window switches in this situation, nothing will happen – you will not hear any motor activity and the glass will not shudder as if it is trying desperately to move. To determine which fuse powers the windows, consult the owner’s handbook and then replace it with a new one.

4) Bad Window Motor

A window motor is required for every power window in order to supply the electrical energy. An additional gear at the end of the power window motor is responsible for connecting it to the window regulator. When you push the up or down button on your door, the window motor is activated, which then allows the window regulator to move the window. If you have a defective window motor, the regulator will not be able to function properly. When the overall window movement speed periodically slows down during ascent, you may be alerted to the probable breakdown of the window motor.

5) Snow and Ice

If you reside in a place where there is a lot of snow and ice, the performance of your power windows may be compromised as a result. The reason for this is that the glass of the windows will adhere to the frames of the windows. When a window and its frame are stuck together, regulators may not be able to dislodge them with adequate power. Even if it is capable of doing so, the regulator will wear out far more quickly.

6) Torn, Loose, or Dirty Window Gasket

The gasket in the window keeps wind and rain out of the automobile while also assisting in the appropriate alignment of the window.

Depending on whether the window is stuck because of dirt or if it is out of alignment, the regulator motor may not be powerful enough to overcome friction and move the window properly. The gaskets and seals on your vehicle may be cleaned, greased, and changed as necessary.

7) Bad Power Window Switch

It is possible that the switch on the side of your door is not operating properly. It takes a small amount of effort to press down on either the up or down portion of the switch to wear out the switch. If you hit the switch too hard or use it too frequently, there may come a moment when it no longer functions correctly. In the event that your power windows are not operating properly, this is the best-case scenario. When compared to the cost of repairing or replacing other potential problems, replacing a power window switch is a bargain.

When you push the window switch on the door itself, compare the answer to the response when you press the window switch on the driver’s door (check sure the windows are not locked by the child safety lock button).

8) Wiring Issues

A set of wires connects the window switch to the window motor, and each of these wires is labeled. Although it is rare for wiring problems to occur in the door, it is still conceivable for them to occur in the future. For example, if another component of your power window system has recently been repaired, it is possible that the technician has accidently damaged or cut one of the wiring harnesses. Return to the mechanic to have them fix it if this occurs, and then repeat the process. Opening the door panel and inspecting the wires running from the fuse box to the door switch itself may also be an option to attempt.

A good rule of thumb is to unplug the batteries before touching any wire to avoid an unintended electric shock from occurring.

9) Damaged Door

Window tracks must be properly aligned in order for the window to travel up and down correctly. The window may become stuck if the door has been damaged in an accident or even if the bolt has come free from the hinge.

10) Dirty Window Tracks

The glass pane moves along metal rails within the door, which is a unique design. Over time, these rails may become soiled by mud and road debris, or the lubricant that keeps the window operating smoothly may become depleted of its lubricant. Try cleaning the window rails and lubricating them with silicone lube to see if it improves anything. Make an effort not to get any of the silicone spray on your painted surface. If you do, wash it off as quickly as you can to avoid further damage.


Power windows are quite convenient, and when one or more of them cease operating, the problem is typically pretty easy to resolve. Depending on the nature of the problem, you may even be able to resolve it yourself. However, safety should always come first – if you’re confused about how the electrical components function, get assistance from an expert technician or just have the repair done at an auto shop.

While the power source is still attached, keep your fingertips away from locations where they may be crushed (gears, for example, or the top of the window, for example).

Car Window Won’t Roll Up? Diagnosis & How To Fix

Consider the following scenario: you’re driving in your car and want to open the window to get some fresh air. Alternatively, a traffic citation. No matter what the explanation is, you’re taken aback when the window doesn’t move! In rainy or chilly weather, it’s aggravating when the window won’t go down, and equally frustrating when it won’t go up. This is a widespread problem, but there are very simple and reasonably priced remedies available. Investigate the how and why of window regulator malfunctions in this section.

What’s inside that door?

An ordinary window regulator is nothing more than a simple metal track that is fastened to the inside of a door. It converts the rotating movement of the window crank handle, or the action of the window lift motor, into vertical movement of the window by reversing the rotational movement. Window regulators are often classified into two categories. The parallelogram type, which in action resembles a pair of scissors, will be found on classic automobiles. A regulator arm’s angle may be adjusted by rotating the crank gears, which activates a pivot point and moves another regulator arm linked to the window track, which in turn moves the window up or down in response.

Similar to a miniature drawbridge, the electric motor moves the cable through a pulley system, which raises or lowers the window as the cable is moved.

Manual window regulator repair and problems

Manual windows are the most straightforward method of raising and lowering the windows, excluding the use of leather straps like those used on automobiles from the Golden Age of the Automobile. This indicates that they are extremely dependable, with few difficulties occurring over the course of the vehicle’s life. Despite this, issues do arise from time to time. Here’s what you should be looking for. When you are cranking the window handle and the window does not roll up or down, either the crank gears are worn out or the window regulator is out of alignment with the window track.

Alternatively, it is possible that the regulator arm is not aligned in its bottom track.

Remove the crank handle with a screwdriver and inspect the gear teeth with the screwdriver.

This occurs when the crank handle does not turn, indicating that the regulator is jammed in place.

The most likely reason for this is because one of the little wheels in the tracks has become stuck on something. Taking off the door panel and replacing it with the handle, spin the door while keeping an eye on the regulator for track snags.

Electric window problems

Assembly of the power window regulator and motor Electric windows are a convenience feature that has become practically common in modern architecture. Even the smallest and most affordable vehicles on the market, such as the Mitsubishi Mirage, are equipped with power windows. Instead of turning a crank handle by hand, a servo motor attached to the regulator or cable system will spin a gear connected to the regulator or cable system with the touch of a button. Power windows are convenient, but they require a little more effort to diagnose.

Try this first

When dealing with an electric window problem, the first step is to press the up/down window switch and listen for the problem. If you are not hearing anything, the fault is most likely with the lift motor’s switch. Start with the switch because it is the easiest and least expensive to repair.

If it’s just the rear windows

Consider a free remedy, such as checking the driver’s door lock-out switch, if the rear windows do not function properly. It is possible that it was mistakenly engaged, and once active, it will prohibit the rear window controls from functioning.

When all windows don’t work

If all of the windows stop operating at the same time, it is likely that a fuse or relay has blown and has to be examined or replaced. The motor of contemporary automobiles, particularly coupes without a window frame, contains a computer module that counts the revolutions of the gearbox so that the vehicle can keep track of where the window is and when it should be stopped from being raised further. If the module loses power or is unplugged, it will not be able to determine whether the window is up or down, and it will need to be reset.

The slow burn out

This can happen if the window motor starts to exhibit signs of wear and tear over time, such as occasional sluggish ascent or absence of movement. Window motors, like any other electric motor, such as a starter, can become “burned out” with time. Even if your car is more than ten years old and still exhibits symptoms, it’s likely that it’s time to have the lift motor repaired or replaced.

Hesitating windows

Finally, “sticky” windows that have a little pause when being raised or lowered are typically not a result of a problem with the regulator. This is most likely owing to the fact that the window guide need some attention. Window frames on the left and right sides of a full-frame window serve as guides for the glass in these windows. To test the guides, raise and lower the window a few times while spraying silicone lubricant into them. Once installed, window regulators are typically forgotten about until they begin to malfunction or break down completely.

Help! My Car Window Won’t Go Up!

It’s a warm night, and you’re driving home in your car with your arm dangling out the window to keep cool. You pull into the driveway, comfortable and unwound, then it occurs — the dreaded window is jammed!

You panic! Despite your best efforts, the window will not budge no matter how hard you try. What should I do? Not to be concerned! The experts at Glass Doctor ® are here to answer any questions you may have about why your car window won’t go up.

My Car Window Won’t Go Up

A jammed automobile window is a difficult situation to be in. If your vehicle is equipped with automated windows (as are the majority of modern automobiles), the issue is most likely caused by defective switches, wiring, or a malfunctioning motor. If you find yourself in this situation, the following checklist will assist you in narrowing down the potential culprit:

  • Child Safety Lock- Sometimes the simplest apparent option is the most effective. Check to see that the safety lock is not activated, since this will prevent the window from opening or closing properly. Examine the Fuses- Consult the owner’s handbook for your car to see where the fuse box is located, as well as the power fuse for the window. Inspect the fuse box and replace any that have been tripped. In this step, you will press and pause the window switch up and down while listening for any sounds coming from inside the door frame. Typically, if you do hear noise, it means that the switch is working well, but the window motor is not working properly. Check It Out- Turn on your car’s windows and pay attention to the gauges on the dash. The volt gauge may show an abnormal jump when the window switch is pressed
  • This indicates that the switch may be faulty. Switched Around- If your passenger or rear window is being recalcitrant, try utilizing the master switch on the driver’s side door. It’s likely that the local switch on the passenger or rear door is to fault if the window is now functional
  • Else Increase the amplitude- If you have access to an amp gauge, you may utilize it to assist you in identifying the problem. If the switch receives electricity and is grounded, the fault is most likely with the wiring or the motor, which are both likely. This means that if you have power to the window motor and it is grounded but it will not roll up, the motor is likely defective.

How to Fix a Stuck Car Window

It is always preferable to seek the guidance of a professional when dealing with a genuinely jammed automobile window. However, if you find yourself with a rolled-down window and an oncoming rainfall, the following troubleshooting techniques are worth attempting: Close the door.

  1. Ensure that the car’s ignition is in the “on” position by pressing the “start” button. Press and Hold- Press the switch down in the desired direction and make sure to keep the button depressed while completing the other steps. Press and Hold- Press the switch down in the desired direction and make sure to keep the button depressed while completing the other steps. Smash the Door- While holding the button down, slam the automobile door open and try again if you are unsuccessful the first time. If the window is able to be raised, do not attempt to lower it again until it has been evaluated by a professional
  2. And Make Use of Your Hand- If slamming the car door with the button pushed does not work, try hitting the door with your fist or another item. Take cautious not to injure your hand or the door frame.

The Glass Should Be Palmed

  1. Ensure that the car’s ignition is in the “on” position by pressing the “start” button. Slice a piece of glass between the palms of your hands and place it between the car door and the window
  2. Allow a buddy to push and hold the window button for you. Lift the Window- Using the palms of your hands, slowly press the window up with gentle pressure until it is fully open. If you’re clutching the window from the top to give it more power, be cautious not to get your hands and fingers stuck in the frame when it comes shut.

These troubleshooting techniques are only intended to be temporary solutions. Do not lower a window until you have the opportunity to have it assessed by a professional. If the windows can be moved back into position, do not lower the window. If your window gets jammed, it is almost always the consequence of some sort of internal mechanical problem within it. An inoperative motor, regulator, wiring or the window switch itself might be the cause of this problem. In the event that your car window becomes stuck, your local auto glass technician will know just how to fix it!

How to Repair Power Windows

Automobile Repair Library, Auto Parts, Accessories, Tools, Manuals and Books, Car BLOG, Links and Index are some of the resources available on this website. byLarry Carley (c)2019 All rights reserved. Most late-model automobiles are equipped with power windows as standard equipment. Window difficulties are rare in most cases, however they might occur when the windows suddenly stop operating or fail to roll back up after being lowered.

Problem: One Power Window Does Not Work

Typically, if one of your power windows does not lower when you press the switch to lower it, the most likely causes are a bad switch, a bad power window motor, a wiring fault in the wiring circuit between the door switch and the door motor, or a wiring fault in the power or ground circuit of the motor. It is best to start with the switch when diagnosing this type of problem because it is generally the simplest component to remove and inspect. Many power window door switches may be easily pryed off of their mounting fasteners in the door panel with a little effort.

  1. Apply gentle pressure to the switch using the flat edge of a dull butter knife to release it by slipping it under one of the edges.
  2. Using a voltmeter, check for voltage at the switch while the ignition is turned on.
  3. Is there no voltage?
  4. This indicates that the switch is getting voltage, but the door motor does nothing when the switch is pressed.
  5. Bypassing the switch and routing electricity straight to the motor is accomplished via a fused jumper wire.
  6. Replace the switch with a new one.
  7. Replace the power window motor with a new one.
  8. Every time the door is opened and closed, the wiring bundle is subjected to significant stretching, and it is not uncommon for wires to break or short out in this location.

Wiggling the harness while pushing the power window switch (key on) will reveal if the window functions or just operates sporadically in some cases (which would tell you the fault is in this area).

Problem: One Power Window Does Not Work but makes noise

Unless you are hearing motor noise (humming or buzzing) from within the door and the window does not move when you push the switch, the switch, motor, or wiring are not the source of the problem. The issue is caused by a malfunctioning window mechanism located within the door. For certain power windows, the window is raised and lowered by use of a scissors linkage connected to a crank mechanism. A rusted, jammed, or damaged connection might prohibit the window from moving and/or cause it to become stuck in place (up or down).

  1. Plastic window drives grow brittle over time and fracture or shatter as a result of wear and tear.
  2. This sort of failure is more common in cold weather, especially if ice has frozen the window shut and the motor is attempting to force it open with excessive force.
  3. Some windows are operated by a steel cable that is used to lift and lower the window.
  4. When using this sort of configuration, you will almost always need to replace the complete window regulator mechanism.
  5. If the window lowers properly but does not rise again, it is possible that it has become detached from the track within the door.

Replacing a Power Window Motor

Because you have to remove the inner door panel in order to replace a power window motor, it is not a pleasant experience. Some door panels can simply be pryed out of the doorframe, but others need the use of special equipment to dislodge the clips that hold them in place. The best recommendation is to consult the OEM service literature for the door panel removal technique so that you can remove the door panel without causing any damage. Once the door panel has been removed, it may be necessary to drill out the rivets that hold the motor to the door frame or window mechanism to make room for the motor.

The replacement motor will be secured in place by new pop rivets or screws that will be installed throughout the installation process.

Problem: All Power Windows Do Not Work

If none of the windows move when you press their switches, the problem could be caused by a blown fuse in the power window circuit, an open or short in the wiring circuit that supplies the power window circuit, or a problem with the wiring harness or module that controls the power windows, to name a few possibilities. First, make sure the fuse is working properly. Please refer to your owner’s handbook for information on where to find the fuse panel (which is often placed beneath the dash on the driver’s side, on the driver’s side kick panel, or on a side panel in the center console.

  1. If the fuse in the power window circuit has blown, there is either a short or an overload in the circuit.
  2. To complete the process, switch on your engine and try to lower one of your power windows.
  3. You should not attempt to replace the power window circuit fuse with a larger amp fuse or to bypass the power window circuit fuse since this is your sole protection against a dangerous overload that might cause an electrical fire.
  4. Attempting to lower a window that has become frozen shut in the winter might result in this and/or the window mechanism within the door becoming damaged.

You will almost certainly need to consult a wiring harness diagram for your car in order to identify and trace the wires in the circuit. Update on the news: October 10, 2012

Toyota Recalls Vehicles for Power windows Defect

Toyota has issued a safety recall affecting about 2.5 million cars to examine and apply special fluorine grease to the Power Window Master Switch on the driver’s side of the vehicle’s windows (PWMS). During operation, the driver’s side PWMS may have a “notchy” or “sticky” feel to it. According to Toyota, if commercially available lubricants are applied to the switch in an attempt to resolve the problem, melting of the switch assembly or the production of smoke may result, which might result in a fire in some cases.

There will be no fee to the vehicle owner for the inspection and repair of the ignition switch.

Customers can obtain further information by contacting the Toyota Customer Experience Center at 1-800-331-4331 (toll-free in the United States).

Easy Car Window Repair and Regulator Replacement (DIY)

Mr. Fix-It-Up-For-The-Family Even though a broken power window can be a costly repair, if you have access to basic car repair equipment and an online service manual, you can often fix it yourself and save a significant amount of money.

Car window repair: Replacing a regulator assembly on automatic windows

To begin power window repair, pry out the switch panel and unplug the electrical connectors from the switch panel. Then you may take off the door trim panel.

Remove the bolts that connect the glass to the regulator (if needed, cut the mechanical cables to raise or lower the glass). Tip the window up and out of the way and place it in a secure location.

Photo 4: Replace the regulator

Remove the bolts that hold the regulator to the door and pull the regulator out through one of the holes in the door. Replace the old regulator with the new one. As a result, one of your power windows is not functional. Rather of having to learn how to manually raise and lower a power window every time you want to get some fresh air while driving, we’ll teach you how to solve the problem instead. First, make sure the fuse is working properly. If that’s the case, the problem is either a malfunctioning switch or motor, or a faulty regulator (see below) (the device that actually lifts and lowers the glass).

  1. In most cases, a business will charge you at least a few hundred dollars to replace the motor/regulator, but you can complete awindow regulator repair and a power window repair in approximately four hours on your own.
  2. You’ll need a basic set of metric sockets, screwdrivers, and a drill, as well as a subscription to an online service manual, which is highly recommended.
  3. Use these recommendations as a general guideline, and consult your owner’s handbook for information on car window repair and replacement.
  4. Remove the trim panel and the vapor barrier by peeling it away from the panel.
  5. Remove the power connector from the window motor by reaching into the door panel and pulling it out (wear leather gloves to protect against cuts).
  6. To use the window switch, turn the key to the “on” position and move the switch up and down.
  7. That indicates that the motor/regulator is the source of the problem.
  8. In order to isolate the problem, you need first download an electrical diagram and inspect the power and ground wires coming to the switch.
  9. Begin by removing the fasteners that connect the window to the regulator (have someone hold the glass while you do this).
  10. After that, remove the regulator bolts or rivets (drill them out) and pull the old regulator out through one of the door panel apertures (see illustration).
  11. Bolt the regulator into place, and then reconnect the electrical connectors for the motor and window switch, as well as the window glass.

Check to see if the window is working properly. If the glass becomes stuck, it may be necessary to unscrew the bolts and make slight modifications to the regulator to free it up. Then reinstall the vapor barrier and trim panel once everything has been tightened.

Car difficulties seldom seem to occur at a convenient time for the driver. This is especially true if you have a car window that won’t go up or close properly. Consider the implications of that for a moment. The vehicle will not be secure, and, in the worst case scenario, the interior of your vehicle will be exposed to the elements. The presence of moisture in a vehicle can cause a variety of problems. Let’s take a look at some of the options for repairing a car window that won’t roll up. Along with that, we’ll release a short workaround for manually activating the power window.

What Does It Mean When Your Car Window Won’t Go Up?

When your automobile window stops operating, it may be really aggravating. Let’s take a look at some of the most common issues you could encounter, as well as how to fix a broken window that won’t go up.

5 Common Reasons Why Your Car Window Won’t Roll Up or Down and How to Fix

There are a variety of factors that might contribute to automobile window difficulties. Let’s take a look at how to fix a car window that won’t roll up, starting with the simplest solution and progressing to the most sophisticated.

1: Engaged Child Safety Switch

When dealing with an automobile problem, it is always best to start with the most obvious reasons first. To begin troubleshooting a window that won’t open, look for the kid safety switch first. While driving, this lockout button, which is located near the driver’s window control panel, prohibits other passengers, including children and dogs, from manipulating a nearby power window while the car is in motion.

Dealing with an Engaged Child Safety Switch

Activating the kid safety switch is simple, so make sure you check it first if any or all of the windows are not working properly. Look for a button that has a window icon crossed out on it.

2: Ignition Switch Position

Another easy remedy to the problem of a power window that won’t go up is to check the location of the ignition switch.

Setting the Correct Ignition Switch Position

If the car is running, this will not be an issue; however, if you wish to roll up or down a window when the car is not running, make sure that the ignition is in the accessory position first. Accessories such as the windows, for example, can get electricity and be controlled in this configuration.

3: Blown Fuse

With easy reasons eliminated, you should investigate whether the problem is with an electric circuit when a driver or passenger window would not roll up or down. If all of the windows are not functioning or only a pair of windows are functional, the most likely cause is a blown fuse. Replacement of the faulty fuse is generally sufficient to resolve the problem.

Fixing a Blown Fuse

First and foremost, find the fuse box. There are several locations where you may find it, including the engine compartment, the glove box, and beneath the dashboard. Some automobiles may even have many fuse boxes, each of which is positioned in a separate location throughout the vehicle. The location of the fuse box may be found in the owner’s handbook. Another option is to contact your local dealer or the manufacturer’s customer support department for assistance. The fuse box should be accompanied with a numbered schematic that clearly identifies the purpose of each individual fuse.

  1. If you are unable to locate a diagram, consult the owner’s handbook or contact a dealer or the manufacturer for assistance.
  2. In the majority of situations, it is a straightforward do-it-yourself project.
  3. The blown fuse should be replaced with a new fuse of the same amperage (also called amp or amps).
  4. If you later discover that the fuse has blown again, this indicates that there is a more serious problem.
  5. In this scenario, you should seek the assistance of a qualified technician.

For those of you who are uncomfortable with your car’s fuses or fuse box, the same may be stated for you. IMPORTANT SAFETY NOTE: Never replace a blown fuse with a fuse with a greater amperage rating than the one that was blown. This has the potential to spark a fire in your vehicle.

4: Bad Window Motor

When a power window won’t raise or lower, it’s possible that the problem is with the window motor. How to Diagnose a Faulty Power Window Motor Turn the ignition to the accessory position without turning the key in the ignition. Try activating the window switch for the problematic window and watching to see if the voltmeter (if your car is equipped with one) in the instrument panel changes even the tiniest bit. Alternatively, when pushing the power window switch, keep an eye out for a little flashing of the interior or external illumination.

Because window motor repair necessitates the use of specific expertise and tools in order to access a door panel, most automobile owners will seek the assistance of a professional.

5: Bad Power Window Switch

If your automobile window will only go down but not up, the problem is most likely due to a faulty window switch or motor. Diagnosing and Repairing a Faulty Window Switch Identification of a faulty window switch is somewhat similar to that of a defective window motor in that it is the inverse of the former. This means that if you activate the switch but do not see any changes in the voltmeter or dimming of the lights, your fault is most likely with the switch itself. Window switches that are not functioning properly require some technical knowledge, so consider taking your car to an auto repair shop for servicing to ensure that it is properly repaired.

How to Get a Power Window Up Manually?

You can find yourself in a position where you need to raise a power window that isn’t working properly. If you notice that piece of the glass is partially visible, you may want to try manually raising the window. Initialize the vehicle by turning it on or shifting the ignition switch to the accessory position. After that, open the door and hold the window in your hands like a sandwich. As you place your hands on each side of the glass, make sure that each palm is as flat as possible. Make sure someone else is in charge of pressing the power window button to raise the window while you are doing this.

Keep an eye out for your fingers or hands becoming stuck at the top of the window when it closes.

What is a Temporary Fix for a Car Window That Won’t Stay Up?

A plastic or rubber window wedge, which may be purchased at local auto parts stores or online, can be used to keep a car window from slipping down. Once the window is completely closed, insert the wedge between the glass and the edge of the door frame. Take care not to damage any molding while doing this. If your car door has a window frame, you can use duct tape to hold a sliding window in place if your car door has one.

Apply the tape to the window frame and the outside edges of the glass when the window is in the closed position. Keep the amount of tape on the glass to a minimum to avoid creating a visual impediment.

How to Cover a Car Window that Won’t Roll Up?

Sometimes, no matter how hard you try, a window simply will not roll up properly. Whenever this occurs, you’ll want to get your hands on a temporary vehicle window kit, which you can get from a local auto parts store or order online. The package includes a plastic sheet that may be trimmed to suit the window opening, as well as specific adhesive to keep the sheeting in place during installation. Some kits are intended to be used in conjunction with a hairdryer in order to shrink wrap the plastic for a more secure fit.

Make certain that any plastic you choose allows you to see through it so that there are no driving dangers.

How Much Does It Cost to Fix a Car Window That Won’t Roll Up?

If you’re merely dealing with a new fuse that you change yourself, the cost of repairing a window that won’t go up can be as little as $20 or less. More sophisticated repairs, such as those that require disassembling the door to gain access to the window motor, can cost anywhere from $250 to $400 or more. It all depends on how easy it is to work on your automobile and how expensive the new components are to purchase and install.

Key Takeaways

When you ask, “Why won’t my window roll up?” you might learn a lot about the situation by doing some investigating. Simple things like a tripped kid safety switch or a blown fuse might be the source of the problem. Still, a window that won’t go up might be the result of a more sophisticated issue, such as a faulty window motor or switch that need the use of a professional electric window repair service to resolve.

How Do Car Windows Work?

A device known as a regulator is used to raise and lower car windows that are contained within channels. Unlike automatic windows, manual windows have regulators that are physically attached to cranks, and turning the crank is the only way to raise and lower the window.

Electric windows have regulators that are connected to motors, but they function on the same fundamental concept as manual windows. courtesy of Lynn Koenig / Getty Images As a result of the differences in components between manual and electric windows, they fail for a variety of causes.

  • Electric windows: Electric automobile windows are normally operated by a reversible electric motor coupled to a regulator that raises and lowers the window glass as the vehicle moves. Various components such as the switches, wiring, and motor might fail, and the regulator can become jammed or fail completely. Manual automobile windows are operated by a hand crank and a mechanical regulator that raises and lowers the window glass within the vehicle’s interior door. If the lubricating oil in the regulator or crank runs out, the gears in the regulator or crank can strip, the regulator can bend and distort, and the regulator can also become stuck due to friction if the lubricating grease runs out.

Two Ways to Roll up a Power Window That Stopped Working

It is occasionally feasible to get a power window to roll up after it has been stuck, depending on the specifics of what went wrong with it. Alternatively, if the switch is working properly but the motor is not, you may be able to physically jar the motor while holding the switch in either the up or closed position. If the switch is working properly but the motor is not, you may be able to get the window to roll up one last time by physically jarring the motor. Here’s how to manually roll up an electric window that has been stuck without using any tools:

  1. Change the position of the ignition key to the on or the accessory position. You’ve got it in the perfect place if you’re able to control the other windows and switch on the radio at the same time. Press and hold the window switch in either the closed or up position for many seconds. It is critical that you keep the button pushed and that you push the side of the window that closes
  2. Otherwise, the window will not close. While holding down the window button, open and slam the automobile door in front of you. If it doesn’t work the first time, you can try it a couple of more times until it works. If it does work, and you continue to hold down the button, the window should roll up automatically. Do not roll the window down unless you are ready to truly address the problem. If the window rolls up, do not roll it back down until you are ready to genuinely fix the problem. It is possible that this temporary remedy will not work a second time. Closing the door and looking for a spot where the door panel appears to be in touch with the sheet metal inside the door may be necessary if the window still won’t roll up. Look on the internet for photographs of your automobile with the door panel removed if you are unclear where to start looking for the correct location
  3. Strike this spot with your fist or a blunt instrument while the switch is pushed to activate it. Precautions should be taken to avoid injuring your fist or damaging your door. If the window is rolled up, keep it in place until you are ready to address the situation. It will be necessary to determine if you have a faulty fuse, switch, or window motor, or to take your automobile to a specialist if the window still does not roll up properly.

The Window May be Out of Its Track

It is possible that the window regulator is malfunctioning or that the window has come off of its track if you hear a grinding sound when you try to roll it up or if you hear the motor operating at all. Following this procedure, if the window is not completely down, you may be able to roll it up.

  1. Change the location of the ignition key to the accessory position. Place your palms together with the window wedged between them while the door is open. Have a friend or family member push the window switch
  2. Apply pressure on the window with your palms and try to raise it up with your arms as well. It is possible that you will need to hold the window from the top in order to exert sufficient power. If you find yourself in this situation, be warned that the window may suddenly begin to move on its own. Watch out for getting your hands trapped in the window as it closes
  3. This can be dangerous.

Even if you have the window all the way down and hear grinding or see the window glass shake back and forth as you try to roll it up, you will not be able to close it without removing the door panel from the window frame. If you are able to remove the door panel, you may be able to raise the window up from the inside while simultaneously pressing the button on the switch.

What Can Cause Electric Windows to Fail?

Blown fuses, broken switches, and burned out motors are the three most common reasons for power windows to malfunction. Aside from wear and tear, it is possible for the window regulator to flex and become jammed, but this is less usual. The solutions to some of these issues are straightforward, while others need the use of specialized instruments and, in some cases, the assistance of a specialist. In the event that your electric windows would not roll up or down, here are some simple troubleshooting options to try:

  1. Check the window safety lock-out switch for proper operation. When the lockout switch is turned on, the windows will not be able to be rolled up or down. Because it’s simple to mistakenly hit these switches without recognizing it, double-check this first. Check the fuses to make sure they are not blown. Check the fuses if none of the windows are able to be opened or closed. Replace any blown fuses and give it another shot. If the fuse blows again, search for a short circuit to determine the cause. Do not use a fuse that is larger than the one suggested. Push the window switch up and down to hear what’s going on. When you push the switch, you should hear a sound from within the door, which indicates that the switch is operational. It’s likely that the electric window motor has failed, or that the regulator has been jammed
  2. Push the window switch while keeping an eye on the dashboard gauges. Another simple method for eliminating the possibility of a faulty switch. The volt indicator on your dashboard should move little when you push the button
  3. If it does, you have a defective motor. Try the other switches to rule out the possibility of a bad motor. Try rolling up or down the passenger side window using the primary switch, which is located on the driver’s side or in the center console, if that doesn’t work. If it works, then the switch on the passenger side is faulty
  4. Swap the switches if at all feasible. In certain automobiles, all of the window switches are similar. This allows you to change one from a window that is functional to a window that is not functional. If the window starts operating again after installing the replacement switch, the switch is faulty
  5. Check for power to the switch. If the switch has power and ground, then the wiring or the motor is the source of the problem
  6. Check for power to the motor. Even though the motor is connected to power and ground, if the window does not roll up or down, the motor is defective.

Check the Lockout Switch

Power window motors and switches can both fail over time as a result of regular wear and tear, but it’s always better to start with the most basic problem possible when diagnosing a power window problem. Power windows include a lockout switch, which may be found on the control panel. If the window lockout button is unintentionally pressed, the windows will get jammed and cannot be opened. The majority of automobiles with power windows are fitted with a safety lockout switch as standard equipment.

This panel can be found on the driver’s door in certain vehicles, while others have it in the center console.

Small children and animals may be prevented from mistakenly opening the windows while the car is in motion by using this safety function.

The symbol on or near the switch varies slightly from one vehicle to the next, but it frequently resembles a window that has been crossed out in some way.

Make an attempt to utilize your windows once more once you have pressed the lockout button. As long as they work, your problem is no longer an issue.

Are the Window Motor Fuses Blown?

In the majority of automobiles, all of the window motors are connected to the same circuit. That means they are all powered by the same fuse, and if that fuse blows, all of the windows cease to function at the same time. If that’s what occurred to you, replacing a blown fuse may be all that’s needed to get your jammed windows to roll back up. When all of the windows become stuck at the same time, look for a blown fuse. In most vehicles, fuse boxes are positioned beneath the dash, in the glove compartment, or in the engine compartment.

  • If your owner’s handbook does not indicate where your fuse box is located, and you are unable to locate it, you may either call your local dealer or search the internet for a photo or illustration of the fuse box location.
  • The majority of automobile fuses are semi-transparent, allowing you to see whether or not the fuse has blown before replacing it.
  • To determine whether or not there is power on both sides of the fuse, you will need to verify with a test light or voltmeter.
  • You should replace a blown fuse with a new fuse that has the same amperage rating as the old one if you discover that it is blown.
  • It is not recommended to replace a blown fuse with a bigger fuse.

Look for Signs the Window Motor Has Malfunctioned

If your automobile window won’t roll up or down, you’ll need to use specialist equipment, and you’ll have to take off both the window switch and the door panel before you can test anything. There are a handful of things you can do to limit down the scope of the problem before you get to that point. If your vehicle is equipped with a voltage gauge, you may use it to determine whether or not your window motor is defective. Some automobiles are equipped with a voltage meter on the dashboard. When the automobile is not running, it normally displays between 12 and 13 volts, and when the engine is running, it displays more than that.

A voltmeter on the dashboard of your automobile may be able to help you rule out a defective window motor switch in the following situations:

  1. Make sure that the key is in the accessory position so that the dash lights and instruments come on
  2. To open your windows, press the window switch. Take a close look to check if there is any movement of the needle on the voltage meter.

When you push the window switch when the engine is turned off, the voltage meter should move even a small amount, indicating that the electric window motor is attempting to function properly. That indicates that your switch is in good working order and that you most likely have a faulty window motor. Also conceivable is that the regulator has been twisted, fractured, or otherwise incapacitated.

The only way to know for certain is to remove the door panel and conduct a visual investigation of the interior. If you do not have the necessary tools, you will need to have the vehicle towed to a specialist.

Attempt to Rule Out Bad Window Switches

Some automobiles have power window switches that are similar for each window. It is necessary to remove the switch from one of the working windows if your car is configured in this manner and you only have one window that does not function properly. Replace the switch for the window that doesn’t work with the switch for the window that does work for the time being, and then try to shut the window. If the window does not close, you will know that the switch is the source of the problem, and you will be able to easily replace it.

How to Check for Power at a Car Window Switch

Further tests are required after this stage and necessitate the use of specialist equipment and experience. If you don’t have the proper tools, such as a voltmeter, and you aren’t comfortable working on your own automobile, it is preferable to just take the vehicle to a mechanic. If you do have a voltmeter, the next step is to make sure that the power window switch is receiving electricity and is grounded. In most cases, a single power terminal is used in conjunction with two ground terminals, as well as two terminals that link to the window motor.

A ground signal should be present on two of the other terminals, and neither power nor ground should be present on the final two.

Pushing the switch in the opposite direction should cause the power and ground terminals to be reversed, and vice versa.

There is an exception in cases when the switch itself does not have power or ground, in which case you have a wiring issue.

How to Check for Power at a Car Window Motor

If the switch appears to be in good working order, the next step is to check for electrical power at the motor. This will need the removal of the door panel. If you have never removed the panel before, you will likely also discover a protective plastic sheet behind the door, and you may also need to remove a second internal panel in order to gain access to the motor and other components. With the door panel removed, you’ll need to use your voltmeter to determine whether or not there is electricity to the motor.

It is possible that the motor is faulty if you sense electricity at it but it does not run at all.

Fixing Manual Windows That Won’t Roll Up or Down

Manual windows are far less complicated than electric windows. Because there are no electrical components in a manual window, there are only two things that might cause it to stop working: stripped gears in the crank or a fault with the window regulator. If the manual window regulator becomes stuck, you may be able to reactivate it by applying fresh oil to the mechanism. In contrast to power windows, there isn’t a quick and simple solution to force a stuck manual window to open for a short period of time.

To determine why a manual window will not roll up, you must first remove the window crank and door panel and physically check the whole window and door assembly.

If the crank freewheels as you spin it, or if it seems like it is grinding, it is possible that the teeth within the crank have been stripped.

If the teeth on the crank are stripped, replacing the crank should resolve the issue.

Make sure the window hasn’t popped out of the channel by checking it again.

In rare instances, you may discover that the regulator has been clogged, has become entangled with something, or that the grease has dried out. When dealing with issues like these, you may be able to roll your window up by loosening the regulator or putting fresh oil to the roller.
