Dash lights not working? (Best solution)

If the dashboard isn’t lighting up at all, your car might have blown a fuse. Removing the old fuse and replacing it should get the lights working again. While the new fuse may do the trick, it could also indicate a deeper electrical problem.

Is there a fuse for the dashboard lights?

Fixing Dashboard Lights: Finding a Blown Fuse The instrument panel fuse box is usually located inside the vehicle, and usually on the driver’s side. There should be a diagram inside the fuse box (or in the owner’s manual) that shows you what each fuse powers.

How much does it cost to fix dashboard lights?

On average a mechanic will charge you $951 to replace the dashboard lights in your vehicle.

What causes dashboard lights to go out?

If it’s light out, make sure that the headlights aren’t turned on. Many headlights often dim the dash automatically when they’re switched on, so this might be the cause of the problem. If that’s not it, look for the dimmer switch. This switch adjusts how bright the dash lights are.

How do I reset my car dashboard?

How to Reset the Warning Lights on the Dash

  1. Open the hood of your vehicle.
  2. Loosen the nut that holds the negative terminal to the battery with the pliers.
  3. Completely remove the cable from the negative battery terminal.
  4. Leave the battery disconnected for 10 minutes to ensure that the computer is fully reset.

How long does it take to fix dashboard lights?

Pick up several packages of new bulbs at an auto parts store before you start the project (replace all the instrument cluster bulbs at the same time), and plan on devoting about two hours to the job. You’ll save the cost of an hour or two of shop time by doing this yourself. Removing dash trim panels is actually easy.

How to Fix Dashboard Lights That Won’t Light

Article in PDF format Article in PDF format It is possible that your vehicle’s dashboard lights will fail or stop working altogether, resulting in impacts that range from being just inconvenient to being potentially hazardous to the driver’s safety. Finding the source of the problem and devising a solution are critical. To begin, check the dimmer switch on the dashboard to determine whether it has been turned down or turned off. After that, look for a blown fuse or a faulty lightbulb. Fortunately, all three issues are rather straightforward to resolve.

  1. 1Start your car and turn on your headlights. Even if you don’t need to start your automobile, you will need electricity to the lights to function properly. Place the key in the ignition and turn the key to the “on” or “accessory” position to start the vehicle. And then activate your hazard lights. 2 Locate the dimmer switch for the lights in your home. Most automobiles are equipped with a dashboard light control switch that may be used to dim as well as turn off the dashboard lights. The control switch, dial or knob should be situated on the console near the steering column, although it may also be a component of the headlight switch.
  • Refer to the owner’s handbook for more information if you are having difficulty locating the dashboard light control switch
  • Advertisement
  • s3 Check to see whether the problem is resolved by adjusting the dial or knob. It’s possible that your dashboard lights were switched off by accident if the switch was accidently touched. Check to check whether the lights on your dashboard come on or become brighter by flipping the switch or turning the dial or knob up.
  • If readjusting the switch does not resolve the problem, you may have a blown fuse or a faulty lightbulb on your hands. Alternatively, the switch itself may be defective, in which case it should be replaced by a qualified mechanic. When you’re finished, turn off your headlights and your car.
  1. 1 Locate the fuse that supplies electricity to the dashboard lights. The position of the fuse box varies from vehicle to vehicle, and some cars have more than one fuse box to accommodate several circuits. Inspect beneath the hood, under the dashboard, and near or in the glove box for any signs of trouble. Having located the fuse box or boxes, remove the lid and inspect the underside of the lid for a fuse labeled “dash lights” or simply “lights.” Once you’ve located the fuse box or boxes, remove the lid and inspect the diagram on the underside of the lid for a fuse called “dash lights.”
  • If you’re having difficulties locating the fuse boxes or the dashboard light fuse, see your owner’s handbook for assistance. In the event that you have more than one fuse labeled “lights,” you’ll need to check each one individually.
  • 2 Check the fuse to determine if it’s blown or not. Remove the fuse that supplies electricity to the dashboard lights by using a fuse puller. Take a close look at the metal strip, or filament, to see whether it is broken, and look for blackening on the fuse—either of these signs indicates that the fuse has been blown. If the fuse appears to be in excellent condition, it should be tested using a multimeter to check that it is functioning correctly.
  • If you don’t have a fuse puller, you may remove the fuse with a pair of needle-nose pliers if you don’t have one. Before you begin removing any fuses, make sure your car is completely off and the key is not in the ignition.
  • 3 Check your dashboard lights and, if required, replace the blown fuses. Take the blown fuse to an auto parts store and replace it with a fuse of the same kind and amperage rating as the one that failed. All of this information is displayed on the fuse itself, and fuses are also numbered and color-coded to make things even more straightforward in this situation. As soon as you get back home, insert the replacement fuse into the appropriate fuse slot until you hear a clicking sound.
  • Reinstalling the fuse box cover and then starting your car and turning on your headlights to check whether the dashboard lights are working Be aware that utilizing a fuse that has a different amperage than the one you already have might result in a fire danger.
  1. 1First, disconnect the battery from the car. It is critical to disconnect the batteries whenever you are working on the electrical components of your car in order to avoid electrical shocks or shorts. Ensure that your car is turned off and that the key is removed from the ignition if you have not previously done so. After that, detach the negative terminal using a wrench before disconnecting the positive terminal. 2 Remove the trim from the dashboard. The procedure for removing the trim differs from vehicle to vehicle. Seek help from your factory handbook or go online for a diagram that corresponds to your exact make and model. Generally speaking, you should start with the lowest trim panel and work your way up from there. Remove the screws that hold each piece of trim in place with a screwdriver, and then peel the trim away from the dash with your fingers.
  • It may be necessary to remove the radio in order to reach the trim on some automobiles. Make a note of all of the screws and lay them aside in a secure location so that you can reinstall them when you’re through
  • 3 Remove the instrument cluster faceplate using a pry bar. The faceplate protects the instrument panel on the dashboard of your car. Remove the screws that are keeping the plate in place, then carefully pry up the faceplate with a nylon pry tool or butter knife that has been wrapped in electrical tape. By pressing in the release tabs on the rear of the faceplate, you may disconnect the switches, controls, and wires that are attached to it, and then remove the faceplate out of the dashboard.
  • The faceplate is held in place by spring-clip fasteners, which should be quite simple to detach. The use of a screwdriver to pry up the faceplate should be avoided since it may easily blemish or harm the dashboard.
  • 4 Remove the lightbulbs from the rear of the instrument panel and place them in a safe place. To remove each bulb from the socket, carefully twist each one counterclockwise and take it out of the socket. Make sure not to spin or pull the bulb too forcefully in order to avoid breaking the glass.
  • If you are unable to pull out the bulbs by hand, you can use a tiny screwdriver to pry them out with. Older automobiles utilize normal bulbs to illuminate the dash, whereas modern vehicles use LEDs to illuminate the dash. In the unfortunate event that your car is equipped with LED lights, you will not be able to repair them yourself. In order to have the complete instrument panel changed, bring your car to a repair facility
  • 5 Replace the lightbulbs with new ones that are identical to the old ones. Replacement bulbs may be purchased at a local car parts store
  • However, they must be of the same electrical rating and size as the original bulbs. It is best not to touch the new bulbs with your hands since the oil may harm them. Place the replacement bulbs in their proper positions while wearing gloves or covering your fingers with a cloth
  • When replacing lightbulbs, it is better to replace them all at the same time, even if some of them are still in good working order. If another bulb fails in the future, you will not have to dismantle the dashboard as much
  • This will save you time and money.
  • 6 Replace the faceplate and trim with the new ones, then reconnect the battery terminals. Simply retrace the actions you did to remove these components in the opposite order. Replace the faceplate and reconnect the trim to complete the project. Connect the positive battery terminal first, followed by the negative battery terminal, as shown in the diagram.
  • To check if your dashboard lights are illuminated, start your car and turn on the headlights when you’ve finished. If they don’t, take the vehicle to a repair shop where a trained technician can identify and repair the problem
  • If they still don’t, call for help.

5. Problem with the Wiring

There are a variety of reasons why your vehicle’s wiring may be experiencing problems, ranging from extended vibrations to large bumps to rats gnawing on cables. Things might go dark if there is an issue with the wiring that is related with the dash lighting. This might be anything as easy as a loose connection, or it could be something more difficult to identify, such as a short in the system or a faulty ground.

4. Dash Light Bulbs are Out

LED lights are used to illuminate the dashes of most modern automobiles, and they are expected to endure for the lifetime of the vehicle. Older automobiles, on the other hand, were equipped with little light bulbs that would ultimately burn out. If you have a problem with burned-out bulbs, you will most likely see them going out one at a time, creating a dark patch on the instrument cluster as they do.

The removal of the gauge cluster is required to replace these bulbs, thus it is recommended that you leave this task to the professionals at an approved dealership repair center.

3. Bad Fuse

This is a more frequent occurrence. The dash lights, like other automotive electrical systems, are protected by a fuse that is designed to blow and shut off the circuit if an excessive amount of power is applied to the system. This helps to keep the circuit’s components safe from harm. Sometimes a fuse will fail for no apparent reason other than the fact that it is old. If, on the other hand, the replacement fuse fails soon after installation, it is likely that there is a more serious problem with the electrical system.

2. Dimmer Switch

What should you do if your dash lights aren’t working but your fuse is fine? Many automobiles are equipped with a dimmer switch that not only turns on and off the dome light, but also allows the driver to alter the brightness of the dash lights in the vehicle. In some cases, if this switch is cranked all the way down, it may appear that the dash lights have been turned off altogether. Even we are occasionally startled by how simple it is to accidentally hit this switch and turn the dash lights all the way down without realizing it until it is done.

After all, a well-illuminated dashboard helps you maintain track of your speed, the engine’s performance, the gas level, and other critical information-including any alerts-while driving. As a result, if the dashboard lights are dim, flickering, or simply not working, it can be annoying as well as potentially dangerous. A issue with your car’s dashboard lighting is typically best left to the professionals to diagnose and repair. A little diagnostic work, on the other hand, can assist you in determining the exact root of the problem, allowing you to explain the issue more effectively.

4. Dimmer Switch

Many automobiles are equipped with dimmer switches, which allow the driver to alter the lighting intensity in the dashboard. It is possible to bump against this by mistake, or another motorist or passenger may have changed it for you. Check this switch first; if adjusting it makes the lights brighter, there isn’t anything else to be concerned with! In addition, check to be that your headlights haven’t been unintentionally turned on; if this happens, the dash lights will often dim themselves.

3. Burned-Out Bulb

The dash lights in most current automobiles are made up of individual LEDs that should last for a long period of time. If you have an older Subaru, on the other hand, the dash may be lighted by a few incandescent lamps rather than LEDs. If this is the case, a blown bulb may result in a portion of the dash lights being turned off. The difference is particularly evident if only a portion of the dash is dim while the remainder of the dash is still lighted.

2. Blown Fuse

Alternatively, if the dashboard lights are completely inoperative, a blown fuse may be to blame Fuse damage may be repaired reasonably easily; however, if the fuse blows again, it may be an indication of a more serious electrical problem that would require the services of a qualified electrician to resolve.

4 Common Dashboard Light Issues

Fuse failure might be to blame if the dashboard lights are not working at all. Fuse damage may be repaired reasonably easily; however, if the fuse blows again, it could be an indication of a more serious electrical problem that would require the services of a qualified electrician to resolve.

4. Blown Fuse

For the vast majority of electrical problems on your automobile, the fuse box is the first place our specialists look for answers. Fuse boxes in automobiles are used to safeguard electronic components from severe electrical surges. In the event that one of them blows, the entire circuit is disrupted. The outcome is that any components linked to that circuit will cease to function. You may either bring your vehicle to Hanson Subaru and have us check your fuses, or you can do it yourself. You may determine which fuse is linked to your dashboard lights if you can locate the fuse box diagram (check the fuse box lid as well as your owner’s handbook for this information).

It is possible that the filament has been fractured, and so the fuse has blown.

3. Burned-Out Bulbs

Additionally, modern Subaru dashboards include video displays that can dynamically update and give you with fresh information, as well as individual LED lighting that are long-lasting and energy-efficient. If you have an earlier Subaru model, on the other hand, this may not be true for you. The incandescent light bulbs that illuminate the analog instruments of older automobiles are nothing special. They’ll ultimately burn out, just like the light bulbs in your house do, so be prepared. Unless you find that certain portions of your dashboard are dark, but others are still lighted, you most likely have only one or two dashboard bulbs that have burned out altogether.

2. Wiring Fault

There’s a good chance that with hundreds of feet of wiring possibly flowing throughout your vehicle there will be several opportunities for wires to become crossed, shorts to occur, and ground faults to manifest themselves. As different wires come into contact with metal frame parts, other electronics, and even other wires, they have the potential to wear through the insulation and produce a short. If you notice any other strange electrical bugs while driving – such as other failed electrical components, or electronics behaving strangely, such as flickering lights and accessories turning on and off at random – you should have a trained technician examine your vehicle’s wiring harness immediately.

1. Bad Dimmer Switch

In relation to your dashboard lights, you have two switches to consider: the headlight switch and the dimmer switch. If your headlights switch was malfunctioning, you would almost probably have problems with your headlights as well as the dashboard lights. Alternatively, if the dimmer switch malfunctions, it might result in your dashboard being dark. Additionally, it’s not uncommon for drivers to accidentally bump the dimmer switch with their knee or elbow when getting into or out of their car.

Before seeking assistance from the Hanson Subaru professionals, make sure that your dashboard dimmer settings are in proper functioning order. If they aren’t, we’ll be happy to assist you in getting back on the road safely in our service center late at night.

Reasons Vehicle Dash Lights Are Dim, Dark, or Flickering

Allow yourself to analyze how essential the gauge cluster on your dashboard is to your overall performance. The ability to view things like speed, engine temperature, and alarms is something we frequently take for granted—at least until we don’t have that capacity anymore. If the dashboard of your Subaru suddenly becomes dim, flickering, or completely dark, your ability to drive safely will be jeopardized. To their advantage, different dash light issues frequently manifest themselves in a diverse manner.

The Symptom: Dash Lights Are Too Dim

The dimmer switch is the most frequently seen source of this issue. This switch or combination of buttons allows you to adjust the brightness of your dash lights to meet your specific requirements. It is possible that the switch or buttons will be bumped, causing the brightness of the dash lights to be reduced above and beyond what is comfortable.

The Solution

This one is simple: just turn the switch to the appropriate position.

The Symptom: Dash Is Partly Dark

Generally speaking, this is an issue that affects automobiles that are a few years old or older, and this is related to the type of technology that was employed. Nowadays, individual LEDs are frequently used to create the dash lights, making it extremely rare to notice a dimming of a portion of the dash that is larger than one of these lights. The instrument cluster, on the other hand, was backlit by light bulbs in previous automobiles. When one of those bulbs failed, the portion of the dashboard that was illuminated would become dark.

The Solution

Changing these light bulbs is not as straightforward as changing the bulbs in your headlights or tail lights. It frequently entails the removal of components from your vehicle’s dashboard. As a result, we recommend that you take your Subaru to the dealership so that qualified technicians can diagnose and repair the problem.

The Symptom: Dash Lights Are Flickering

Despite popular belief, your Subaru is not attempting to host a party. In the majority of cases, malfunctioning alternators are to blame for flickering dashboard lights. Additionally, the alternator is responsible for the proper operation of the electrical components in your car, in addition to charging the battery. If the alternator is failing, it may not be able to provide adequate current to all of the components on a consistent basis.

The Solution

As soon as possible, take your Subaru to a service shop for repairs. The failure of an alternator is really terrible news for a variety of reasons! It is possible that it will not enable your battery to recharge sufficiently, causing it to progressively deplete to the point where you will want a jump start to get things moving again. Furthermore, because the electrical current delivered to the spark plugs is what generates the spark, your engine may be rendered inoperable if the alternator fails completely.

The Symptom: Dash Lights Are Dead

Generally speaking, if the dash lights are entirely dark, it is reasonable to conclude that the problem is electrical in nature. The most likely cause of this is a blown fuse, which is intended to safeguard the circuits in the event of a spike of electricity.

However, it is possible that the problem is caused by deeper wiring faults. These issues might still result in the fuse blowing, and they could continue to exist even after the fuse has been replaced.

The Solution

To begin, locate the fuse box in your car and consult the owner’s handbook to determine which fuse is responsible for the dash lights. Make certain that the car is switched off and that the keys are not in the ignition before removing the fuse with pullers or a pair of pliers from the ignition. Hold it up to the light once you’ve taken it out of the box. It will be necessary to replace the fuse if the internal filament has been damaged. Install a fuse with the same amperage rating as the one you removed and hope it works!

Instead, your vehicle is most likely experiencing an electrical problem that has to be addressed.

Why Are My Dashboard Lights Going Out?

If the dashboard lights in your automobile have gone out, it might be difficult to view important information in the instrument cluster. Find out what may be causing this issue in the section below! As with most things involving the electronics in your automobile, it may be preferable to delegate this task to a professional for your convenience. We can determine exactly what has gone wrong and correct it, allowing you to spend your valuable time doing something else with your time. Find out what could have gone wrong and what it will take to correct it in the sections below.

4. Dimmer Switch

The dimmer switch, which is sometimes situated low on the dashboard or on the door panel, where it might be accidentally hit, allows you to change the brightness of the dashboard and other interior lights in your car. The presence of ambient light in most city driving situations indicates that the brightness should be set to the maximum setting. However, on dark, rural roads, the dashboard may become uncomfortably illuminated, making driving difficult. The dimmer switch comes in handy in this situation.

Before you resort to more harsh tactics, locate the dimmer switch and ensure that it is set to the maximum setting.

3. Blown Fuse

In your automobile, the electrical wiring is routed via a fuse box, which is similar to the breaker box in your house or office, which protects the components from being damaged by unexpected surges of energy. Such a surge might be caused by a fault in the wiring or a defective accessory. When an excessive amount of current flows through a circuit, the fuse will explode, terminating the connection before any harm can be done to the circuit. The fuse linked with your dashboard lights should be checked if your dashboard lights aren’t operating properly.

2. Burned-Out Dashboard Bulbs

While current automobiles are equipped with video dashboard screens and LED-backlit dashboards that are designed to last longer, basic light bulbs located beneath the dashboard are frequently used to give lighting. Furthermore, they will ultimately burn out, just like any other standard light bulb. It is recommended that you visit our service facility for a professional repair in this scenario. Specialized knowledge and tools are required to get access to the rear of the instrument cluster without causing damage to your vehicle’s interior.

Best of all, we have all of the components you need for your Toyota in stock, including light bulbs, so you can get back on the road as soon as possible.

1. Wiring Fault

If the bulbs are in excellent working order, the fuse is intact, and the dimmer switch is set to the maximum setting, it is possible that the electrical connection to the instrument cluster is faulty. This is extremely improbable, although it is not unheard of. Did you know that rats have been known to seek out automobiles in order to gnaw on the electrical wire harness? Wires can also break when they brush against other wires or metal components, or something can be jarred out of place if there is a large impact.

Gauges in Your Car Not Working? Try These Fixes

A complicated tale is told by the dashboard gauges in your automobile, which include everything from your current speed to the status and health of your engine, and even whether or not certain features such as your headlights are turned on. There are a variety of gauges available on various cars, and some instrument panels are far more intricate than others. When the gauges on your automobile cease working, though, it is not a situation you can afford to overlook for very long. The fault might be with the gauge itself or a damaged sensor, but all of the gauges failing at the same time is usually indicative of a blown fuse or a malfunctioning instrument cluster, according to the manufacturer.

  • If none of the gauges operate at all, the problem may be caused by a blown fuse or a malfunctioning instrument cluster. If all of the gauges are reading low or unpredictable, it is possible that there is a problem with the voltage regulator that supplies the instrument cluster. If all of the gauges are set to the highest possible reading, it is conceivable that there is a wiring problem or a defective instrument voltage regulator at fault.
  • If the oil pressure, coolant, charge, or gas gauges do not function properly or function in an unpredictable manner, the fault is most likely with the gauge, wiring, or sender. Speedometers are unique in that some of them rely on physical cables rather than sensors, therefore a broken cable or stripped gear may be the cause of a malfunctioning speedometer.
  • This typically signifies a blown bulb if one or more of the warning lights do not activate when you initially turn the key in the ignition. Initially, if none of the lights illuminate at all, examine the fuses and cabling leading to the instrument cluster. When a warning light illuminates and remains on while the engine is running, it typically signifies that there is an issue with that particular system.

Gauges in Car Not Working at All

A wide variety of instrument cluster designs and combinations exist, but when all of the gauges in a car cease working at the same time, the problem is almost always a problem with the fuse or the wiring. The first step in troubleshooting this sort of problem is to locate the fuse that is linked with the instrument cluster or gauges in question. When the ignition key is switched to the on position, the fuse should have power on both sides of the circuit. In the absence of proper automotive diagnostic instruments or if you don’t feel confident performing a diagnostic like this, you may check this using a cheap test light or multimeter, or take your car to a repair.

The instrument cluster must normally be removed in order to accomplish this, which may be a time-consuming and complex task in some cars.

The complexity level is generally comparable to that of installing a new vehicle radio, so if you’re familiar with that task, you should be able to accomplish this one with ease.

What If the Indicator and Dash Lights Don’t Work Either?

The fact that your gauges are not working, as well as your dash lights and indicators, is an indication that you may be experiencing a grounding problem in your vehicle. For the sake of this section, assume that you have already examined the gauges fuse and established that it is functioning properly. Typically, when an instrument cluster is improperly grounded, the gauges and dash lights will fail to function or will only function sporadically.

In some circumstances, you may be able to inspect the ground by peeking up beneath the dash with a flashlight, but in most cases, you will need to remove the instrument cluster.

What If the Gauges Seem Erratic or the Needles Are Pegged?

In most cases, when the gauges appear to be moving erratically or when they are pegged at their maximum possible reading, the problem is caused by a faulty component such as an instrument voltage regulator or a faulty ground. It is most often the case that a defective instrument voltage regulator is to blame for erratic readings, or gauges that appear to read uniformly low. Depending on the situation, you may be able to remove the regulator, clean the connecting terminals, and then replace it.

It is important to check that the ground is securely fastened and free of rust or corrosion if you have been successful in locating it either visually or with the aid of a wiring schematic.

The Trouble With Electronic Instrument Clusters

In certain instances, you may discover that the entire instrument cluster is malfunctioning and has to be replaced. As an example, if you have an electronic instrument cluster that does not contain distinct gauges that receive independent inputs from discrete sending units, a total failure of all of the gauges will almost always result in the need for the whole cluster to be replaced. Early electronic instrument clusters included digital readouts similar to those found on an LCD alarm clock, however the current counterpart frequently resembles analog gauges in a far more sophisticated manner than their predecessors.

What If Just One Gauge Doesn’t Work?

Any time only a single gauge fails to function properly it indicates a malfunction in the gauge, its wiring, or the transmitting device. If you are confident in your ability to locate and remove transmitting units and sensors, you can do a self-diagnosis on this sort of problem. A mechanic will be required if the vehicle is not repaired. Consider your coolant temperature gauge as an example. The diagnostic technique begins with the identification and removal of the transmitting unit. When the ignition is turned on, the gauge should read “cold.” If you connect the transmitting unit wire to ground, the gauge should change from cold to hot to indicate the connection was successful.

It’s possible that the gauge is defective if it doesn’t move when you ground out the sensor line, although this is unlikely.

When It’s the Speedometer Not Working

While all gauges may be either analog or digital in nature, speedometers are unusual in that they can be either mechanical or electrical in nature, making them the most versatile of all. All other dash gauges are wired to sensors or transmitting units, however your speedometer may be connected to a speed sensor or a physical cable, depending on how it is configured. If a vehicle is equipped with a cable transmission, the speedometer is physically connected to the transmission by means of the cable.

Depending on how the cable breaks, the gauge may not move at all, or it may move sporadically with a little jolt.

In many instances, this will also necessitate the removal of the instrument cluster itself.

Malfunctioning Speedometers and Speed Sensors

Speed sensors have replaced cables in the majority of modern automobiles and trucks, with the changeover beginning in the 1990s. There are certain automobiles that include both a speed sensor and a cable; in this instance, the cable is normally used to drive the speedometer, while the speed sensor or wheel sensor is used to inform the computer about how fast the vehicle is travelling. There are two ways to find out for sure what your automobile has: either search up your car’s make, model, and year online or physically inspect the rear of the instrument cluster with your hands.

  1. In automobiles equipped with speed sensors, the existence of a cruise control system provides the most convenient means of determining if the sensor or gauge is malfunctioning.
  2. If you discover that your cruise control is operational but that your speedometer is not, you should investigate a faulty speedometer.
  3. In some cases, the electronic control unit (ECU) may be failing in a less usual scenario.
  4. Using specialist testing equipment, they will also be able to do an actual test on the speed sensor in question.

What If It’s Dashboard Warning Lights That Don’t Work?

However, although many automobiles and trucks are equipped with gauges that provide detailed information on everything from the charging system’s health to the coolant temperature, certain cars and trucks are equipped with warning lights. They are intended to glow when the input from a transmitting unit or sensor is outside of the expected range. Consequently, instead of a needle indicating that your coolant temperature is 230 degrees Fahrenheit and in the red danger zone, a warning light will flash to indicate that the coolant temperature is higher than it should be.

If one or more of the lights fail to illuminate, it is most likely due to the fact that the bulbs have burned out completely.

In the same manner that a non-working gauge is diagnosed, you will need to check for power at the relevant fuse and make sure that the instrument cluster ground is in good working order with this problem.

If all of these items are in order, the problem is likely due to a faulty transmitting unit or wiring.

Figuring Out Why Dash Gauges and Lights Don’t Work

If you’re working with gauges or lights, the fundamental troubleshooting technique will always be decided by the amount of failures that occur at the same time, regardless of the type of instrument. Consequently, if only one gauge or light quits working, you will follow one fundamental method, and if everything stops operating at the same time, you will follow another basic procedure.

  1. When all of the gauges or warning lights in your automobile stop working at the same time, the problem is usually caused by a fault that all of the gauges and warning lights have in common
  • First, make sure the fuses are working properly. Depending on the manufacturer, the fuse may be named gauges, cluster, or anything else similar. When the ignition is turned on, this fuse should be able to supply electricity to both sides of the circuit. If the fuses appear to be in good working order, then check for power at the instrument cluster. If the instrument cluster is powered, then look for a grounding connection. Bad ground connections might result in total failure or readings that are inconsistent. Even if everything else fails, it may be necessary to replace the instrument cluster itself.
  • The problem is either a faulty sensor or a faulty gauge when only one gauge or light ceases to function properly.
  • It is necessary to find the sensor that is connected to a single malfunctioning gauge or warning light before you can diagnose the problem. Typically, the first step is to disconnect the sensor from the rest of the system. Separating the sensor from the gauge or attaching it to a grounding point, depending on how the gauge is designed, may allow you to test the gauge’s functionality. In terms of gauges and sensors, the diagnostic technique varies depending on the application. Sometimes you may discover that the problem was caused by a faulty connection
  • In this instance, you should contact the manufacturer.
  • In the case of a physical cable-connected speedometer that does not function, the problem is either a damaged connection or a faulty speedometer.
  • Diagnosing this problem is rather simple if you can determine where the speedometer cable links to the transmission, which is not difficult to accomplish. Turning the end of the cable that inserts into the gearbox by hand with your fingers should cause the speedometer to move
  • However, this is not guaranteed. Disconnect the speedometer cable from the speedometer and manually spin it if the needle does not move. It’s possible that the cable is internally damaged if you manually spin one end and don’t see the other end revolve. If it does turn, this indicates that the speedometer is malfunctioning.

4 Reasons Car Dashboard Lights Not Working

On the Subaru dashboard, you’ll find a slew of gauges that provide you with a wealth of useful information, from the speedometer to the temperature gauge to the check engine light and a variety of additional warning indicators. Therefore, it nearly goes without saying that dash lights that are flickering or completely dark should raise suspicion. There are a variety of reasons why this may occur. The good news is that the symptoms of the various reasons are typically distinct from one another.

That is one of the reasons why we have compiled this list.

Schedule your Subaru service appointment as soon as possible to ensure that you get the most out of your car.

4. The Lights Are Dim

If the dash lights on your Subaru are either excessively dim or totally turned off, you may be in for a treat. If it’s daylight, the first thing to check is that the headlights haven’t been unintentionally switched on. When the headlights are turned on, the dash lights are frequently dimmed automatically. Although the headlights are turned off, you may still be dealing with a rather straightforward issue. Look locate the dimmer switch once you’ve double-checked all of your lights. This switch accomplishes precisely what it says on the tin.

The problem should be resolved by adjusting the dimmer switch.

3. The Instrument Panel Is Partly Dark

If you’re driving a recent Subaru model, you’re unlikely to encounter this issue because the vehicle is likely to be fitted with LEDs that operate independently of one another. However, as late as a few years ago, incandescent light bulbs were frequently used to backlight the whole dashboard. If one of these bulbs fails, the area of the instrument cluster that it illuminates will be dark as well as the rest of the instrument cluster. If anything like this happens to you, it’s better to leave the repairs to the professionals to avoid more damage.

2. The Instrument Cluster Is Completely Dark

If the dashboard does not light up at all, it is likely that you have blown a fuse. To get things working again, remove the old fuse and replace it with a new one of the same type. This should fix the problem. In contrast, if the replacement fuse fails not long after it is installed, it may indicate the presence of more serious electrical problems that need to be investigated.

Volkswagen Dash Lights Not Working

Dash lights allow you to read crucial information on your instrument panel, so if they stop working, you need to have them repaired as soon as possible. Dash lights that do not operate properly might cause drivers to overlook critical information about their vehicles. It is advisable to begin by assessing the problem one step at a time. The simplest remedies should be the first ones you test. For example, there is a dimmer button on the dashboard, so your first step should be to check sure it has not been turned down.

A blown fuse might cause the lights to not function properly.

Checking more than one fuse box for the fuse that controls the dashboard lights may be necessary.

To determine the appropriate position of the fuses, see the fuse diagram printed on the box lid. Any blown fuses should be replaced with the appropriate replacement fuses. Third, by removing the faceplate from the dashboard panel, you may check the lights in the dashboard for malfunctions.

  1. Removing the screws that keep it in place and looking for the bulb on the rear of the panel are both good ideas. Pull it out of the socket with care by twisting and pulling it. Take a look at it to see if it has filament damage. If the bulb is discolored or black, it should be replaced. Make sure you’re using an exact replacement bulb. Before you change the bulb, apply a little amount of bulb oil to the base of the bulb. In this way, the bulb’s life expectancy will be extended. If you are unsure whether or not you require a new bulb, bring the old one with you when you go to purchase a replacement. The majority of shops will test the bulb for you. Reinstall it with a little bulb oil on the base if the condition is good
  2. Otherwise, remove it completely.

Even if you have tried all of these suggestions and your dashboard lights are still not working, it is possible that you have an electrical problem that requires further expert attention. You should take your Volkswagen to the dealership or repair shop closest to you.

Dim, Flickering, or Dead Car Dash Lights? 4 Possible Causes

Several critical pieces of information are shown on your dashboard. The gauge cluster tells you how quickly you’re traveling, how much petrol you have left, whether or not something is incorrect that requires your attention, and much more. As a result, dash lights that aren’t functioning properly might be quite dangerous. We at Nate Wade Subaru want to assist you in becoming more knowledgeable about your car, which is why we’ve created this website. Below, you’ll discover a list of possible causes of dash light difficulties, as well as some accompanying symptoms that may help you narrow down your search for the source of the problem.

4. The Dash Is Completely Dark

If the instrument panel is entirely dark, the first thing to check is whether or not a fuse has blown. Consult your owner’s handbook to determine which fuse is responsible for the dashboard lighting. After that, make certain that the car is off and that the key is not in the ignition. Remove the right fuse by opening the fuse box and pulling it out with the puller. In order to verify the wiring inside, hold it up to a light source. If the fuse is damaged, it should be replaced with a new one of the same size and amperage.

It’s also possible that the alternator, battery, or another electrical system fault is to blame if all of the electrical components have failed.

3. The Dash Lights Are Dim

The dimmer switch located within your car is used to control the brightness of the dash lights in your vehicle. It’s possible that you accidently touched the switch, causing the lights to become very dim. Finding and altering the switch may be the solution to your difficulties. Alternatively, your headlights may have been turned on without you realizing it. When the headlights are turned on, the dash lights are typically dimmed.

2. The Dash Is Only Partly Lit

Nowadays, many dash lights are made up of individual LEDs that are expected to endure for the whole life of the car. Older automobiles, on the other hand, featured dashboards that were backlit by a few of light bulbs. Whenever one of these lights goes out, the portion of the dash that was formerly lighted by that light will become dark. If this happens, we recommend that you take your Subaru to a repair shop so that the bulb may be changed. Most likely, this will require disassembling the entire gauge cluster from the dashboard, which is a procedure that’s best left to professionals like the factory-trained specialists at our dealership repair facility.

1. The Dash Lights Are Flickering

The alternator is responsible for recharging the battery while your Subaru is in motion, but it also performs other functions. It also provides power to the electrical components of your car, such as the dash lighting, as well as the radio. Having your lights flicker might indicate that your alternator isn’t performing properly. This might also have an impact on other electrical systems, such as the headlights and radio.

It might potentially indicate that the battery isn’t receiving enough charge, resulting in your Subaru being difficult to start. If this occurs, you should take your Subaru to the dealership to have the alternator replaced.
