Intermittent Wiper problems? (Best solution)

One of the quickest indicators that a problem exists with the intermittent wiper relay is when the wipers are not intermittent and only work at one speed. If you make a change in the settings and the wipers don’t react, it’s most likely due to a malfunction in the intermittent wiper relay.

What causes intermittent wipers to stop working?

The two most common failures are: A broken turn signal “canceling” mechanism that won’t shut off the “blinkers” after a turn, A partial or complete loss of intermittent wiper control.

Why do my wipers stop and start?

The problem you are describing likely stems from an intermittent electrical fault in the wiper circuit. The windshield wiper system uses a small electric motor to move the wiper arms that you see on the windshield. That electric motor is controlled through a switch, relay, fuse, and wiring.

Why are my windshield wipers glitching?

There are various causes for skipping wipers. The rubber may be dried out or corroded from salt or sun. They also could be bent in a way that prohibits correct movement across the windshield. Another cause could be your windshield if it has amassed a film from tree sap or gathered acidity from rain.

What does intermittent mean on windshield wipers?

Most wipers have a low and a high speed, as well as an intermittent setting. When the wipers are on low and high speed, the motor runs continuously. But in the intermittent setting, the wipers stop momentarily between each wipe.

Why are my wipers only working on high?

If the reading is made only on the high-speed terminal, the switch has failed. Inside the switch are a number of terminals that are sprung to make contact as the control is turned or slid like a lever; these contacts can lose their “springiness” and fail to make contact.

How do you reset a windshield wiper motor?

Use a socket wrench to remove the nut located at the center of the wiper motor. This nut connects the arm linkage to the motor. Turn the wipers on, then back off, so the motor completes a full cycle and returns to the correct park position. The blades will not move since the linkage has been disconnected.

How do you know if your windshield wiper motor is bad?

Common signs include wiper blades that move slower than programmed, only have one speed, do not move at all, and don’t park in the correct position.

What to do when wipers stop working?

Simply, replace the culprit, and reassemble. If the problem is with the rear wiper system, getting to the wiper motor can be more difficult with far more trim to remove than with a front system. You may elect to consult your mechanic for help.

How do you stop windshield wiper judder?

Some websites recommend wiping your wiper blade edges with rubbing alcohol at least once every month. They claim, this can not only reduces shuddering but also gets rid of debris, grease or loose bits of rubber from the blade.

How do you lubricate windshield wipers?

To eliminate this noisy issue, first clean your windshield wiper blades with a bit of soap and water and then coat the moving parts with some spray silicone lubricant. The silicone will keep the wiper blades running smoothly and quietly throughout the winter months.

Where is the intermittent windshield wiper relay located?

In these cars, relays are frequently mounted separate from the fuse box, usually under dash near the steering column.

Who invented intermittent wipers?

Robert Kearns, 77, Inventor of Intermittent Wipers, Dies. DETROIT, Feb. 25 – Robert W. Kearns, the inventor of intermittent windshield wipers, who won multimillion-dollar judgments against Ford Motor and Chrysler for using his idea, died on Feb.

What controls windshield wiper speed?

Now, virtually all automotive wipers are controlled by a microprocessor. Many wiper systems in cars today use a rain sensor to detect the speed at which the raindrops are falling on the windshield. A microprocessor evaluates the signals from the sensor to calculate the speed at which the wipers should move.

What int means in car?

INT: This turns your wipers to intermittent mode, when it’s doing more than misting, but not quite raining hard enough for low. LO: Low speed for your wipers.

How to Fix Intermittent-Wiper and Turn Signal Problems on the Multifunction Switch

The most typical faults on the multifunction switch in late-model automobiles are intermittent wiper controls and malfunctioning turn signals. You may save money by completing the repair yourself; it isn’t nearly as difficult as it appears.

Tools Required

This lever, which was previously known as a turn signal or blinker switch, now controls headlights, high beams, emergency flashers, wipers, and washers, among other things. It’s no surprise that it’s now referred to as the multifunction switch (MFS). Unfortunately, the MFS has a significant failure rate compared to other systems.

The two most common failures are:

  1. A malfunctioning “canceling” system for the turn signal that will not turn off the “blinkers” after a turn
  2. A partial or total loss of control over the intermittent wipers
See also:  Test an alternator - the safe way? (Suits you)

The following tools and materials will be required to resolve these two issues: a shop manual, a digital voltmeter, and potentially some Torx bits

Locating Your Vehicles Multifunction Switch

The MFS may be found behind the steering wheel on the majority of late-model automobiles, hidden behind the plastic coverings. If that is the case, you may complete this repair in approximately an hour and save the money that would have been spent on an hour or two of shop labor. However, certain older cars necessitate the removal of the airbag and steering wheel, which is a procedure best left to a professional. See whether your MFS may be found in a shop manual by searching online (you can find shop manuals with an online search).

Here are 100 automobile repair and maintenance activities that you can complete on your own.

Project step-by-step (4)

Always disconnect the negative battery connector and wait 15 minutes for the airbag system to shut down before beginning work on the steering column or other parts of the vehicle. Then unscrew the screws and pull the plastic covers off the screws. Keep track of the screws by doing the following: Using the screws that hold the bottom half of the steering column cover together, remove each screw and make a note of the length, thread style, and location of each screw. They will have to return to the same location.

Step No.

All About the Multifunction Switch

The headlights, flashers, wipers, and intermittent windshield washers are all controlled by multifunction switch levers. Hex-head or Torx screws are often used to secure the MFS in place. Remove them, pull out the switch, and unplug the electrical connector from the wall outlet. If the problem is caused by a malfunctioning canceling mechanism, you will need to replace the complete MFS (auto parts store or dealer). If the issue is defective intermittent wiper operation, the following steps should be taken: If the intermittent wiper operation is problematic, use a multimeter to examine the connections on the rear of the MFS for resistance (ohms) readings for each setting on the intermittent wiper dial.

Then compare them to the instructions in the handbook.

If your resistance readings are incorrect, the shop manual will instruct you to do so.

Look for the phrase “multifunction switch repair” on the Internet. The following options are available if neither strategy works: If you are unable to remove or clean the MFS, replace the complete device and reapply the covers.

Ford F150 Wiper Fix Procedures

Are your windshield wipers not working properly? Do they come on by themselves or do they not function properly? You don’t have to search much farther. Finally, we have a solution to this problem. We would like to express our gratitude to Keith Vicker, who granted us permission to republish this piece. The original version of this technical article appeared on It is primarily meant for Ford trucks, although it may also apply to other Ford vehicles, depending on the circumstances.

Tools Required

  • Two shop towels, one shop rag, and Q-tips are included. Flat-blade screwdriver with tiny flat-bladed blades
  • Dielectric oil
  • Lid or bowl (for storing small parts)
  • Additional spray-can straws
  • Make contact with a cleaner. Cleaner for the brakes

Before beginning this method, make sure that the ignition is turned off and the key is removed. The end cap should be removed as the following step. Make use of a pointed, flat instrument to carefully peel the cap away from the stem. As soon as the end cap has been removed, hold the wiper switch in place while you unscrew the single Philips screw. Wait a minute before you turn out the light! Before you remove the rotating switch cover, insert your palm underneath the whole assembly as indicated in the illustration.

Apply a generous amount of the dielectric grease on a Q-tip.

if you are having trouble turning the screw, remove it and try starting it in a new position.

Take pleasure in your exorcized windshield wipers.

HOW TO: Intermittent Wiper Problem Fix. AKA TSB Fix.

A how-to guide on how to repair the Technical service bulliten 04-15-2, which is characterized by the loss of intermittent wipers or the loss of the park function. The solution is actually fairly easy, and it will only take you 20-30 minutes of your time to complete. Here is a list of things you will require. 3/8-inch Ratchet Reducer for 6″ or 8″ 3/8 extension 3/8 to 1/4 5/16 socket (if it’s a 3/8 socket, you don’t need the reducer). 3/8 to 1/4 5/16 socket. Needle Nose Pliers are a type of pliers that have a needle nose on one end and a flat on the other.

  • F5TZ-14N089-B is the Ford part number.
  • Step one is to remove the fuse panel door and unbolt the four 5/16-inch bolts that secure the lower dash to the floor.
  • The red circles indicate the locations of the bolts that must be undone in order to remove the panel from the wall.
  • Because there is no need to remove the OBD II port or the Hood Release cable, you don’t have to be concerned about those components.
  • Find the two bolts that hold the fuse panel to the steel mounting bracket and tighten them down.
  • Both the bolts and the relay are located in the same location.
  • As a result, the driver’s door is on the left, while the passenger’s door is on the right.

The fuse panel will pop out with a little wriggling and giggling on the part of the user.

Don’t be too harsh or you could pinch or yank a wire, which is never a good thing.

The Rear Wiper Relay R18 is on the left, while the Front Wiper Relay R19 is on the right.

Step number three.

R18 is the Relay for the Rear Wipers (also known as the Relay Closest to the Door) and R19 is the Relay for the Front Wipers (also known as the Relay Closest to the Door) (Closest to your Head Unit) Please refer to your handbook for assistance if you are confused whether relay is R18 or R19.

* The grey relay represents the old relay, while the black relay represents the replacement*.

Step Four: To reinstall the relay, align the pins and push it back into the socket.

With one hand, align the pins and support the fuse panel, while the other pushes the relay into position.

Step FiveIn order to install the fuse panel, you must first connect the bottom clips and then put the panel into the bracket. Put the two 7mm bolts, tighten them down, and then replace the lower section of the dash on top of them. And there’s the end of that unpleasant problem.

intermittent wiper problem solved : relay

Hello everyone, I’m writing to express my gratitude for your time and consideration. I’m starting to feel like a complete moron. I’d acquired an unusual intermittent-wiper problem, in which the wipers would operate perfectly in normal and high-speed mode, but would not come on or park while in wash-wipe mode for no apparent reason. As a result, I replaced the stalk/switch with a previously used one in case the switch was defective. There has been no change. In the event that the park switch at the wiper motor was malfunctioning, I replaced it with a previously owned unit.

  • While playing about with the panel cover today, I removed the relay at FR17, which is labeled “Front Wipers” on the panel cover.
  • “Hmmm,” I thought to myself, “perhaps FR17’s relay is just in charge of the intermittent function.” So I brought the replay inside the house and peeled the cover off.
  • After removing the cover, I glanced inside one of the thin ends of the relay and noticed that the little contact arm was in the down position, which was touching a connection.
  • The arm popped a little as I was doing this, and I realized it had been stuck for quite some time.
  • It turned out to be a faulty relay.

Intermittent Wipers not working properly

You need either upgrade your browser or switch to another one. 1700 Ownership of a Buick Buick I have a 2004 Lesabre Limited, and my windshield wipers operate properly in either the high or low settings, but when they are set to the intermittent position, they wipe once or twice and then stop working completely. They do not stutter or come to a halt in the middle of a wipe. What is the mechanism that regulates the timing of the intermittent wipers?

  1. Any assistance would be greatly appreciated.
  2. A good guess is that it is the multi-function switch on the steering column, which is number 36 on this diagram (hash=item 3f306403e4 vxp=mtr on this diagram).
  3. You may look at your wiper motor more to see whether it contains the circuit board, and if it does, it should be a simple fix if it’s inexpensive enough.
  4. We hope this information is useful; please let us know if you have any more questions.
  5. They do not stutter or come to a halt in the middle of a wipe.
  6. A timer module on the switch, is that what you’re looking for?
  7. Are these wipers equipped with rain-sensing technology?

If this is the case, the delayed cycle selected by the rotation of the stalk switch is not renewed until the rain-sensing infrared beam informs the unit in the mirror base that there is water on the windshield, at which point the delayed cycle is reactivated.

Unless you’re in a dry location, the only way to tell if the rain-sensing wipers are activated is if they swipe once when the car is first started.

Start the car with the delay set to a short wait time and pour some water on the region of the windshield where the problem is occurring.

In addition, make certain that the region is free of road oils.

1700 Ownership of a Buick Buick Thank you for taking the time to respond.

In my case, the problem occurred while traveling through snow, and my windshield wipers kept stopping even though they were on a delay setting.

1,6471338 Florida’s Central Region Ownership of a Buick Buick Electra 1998 130,000 Miles from Park Avenue to the base of the mountain When they came to a halt, did they automatically restart, or did you have to turn the wipers off completely?

1700Buick OwnershipBuick OwnershipBuick My knowledge of whether they would have restarted is limited due to the fact that I was driving at the time.

I hope this helps.

It is true that the auto wipe does not appear to detect moisture as effectively as I would want in the bottom three settings, at least in certain moisture circumstances.

Snow does not adhere to surfaces and convert into droplets of water.

The substance may be greasy, preventing it from “wetting” the windshield and making contact with it, which would otherwise allow the infrared beam to pass through at that location.

Without any water droplets on the outside, the infrared beam that is reflected back to the sensor from the surface of the glass on each side has a specific intensity when there is no water droplet on the outside.

When the light brightness lowers to a certain level, the sensor triggers the delay circuit, which begins the process of waiting for the delay period specified by the twist switch.

The possibility to turn off the rain-sensing feature and just have standard delay would be appreciated.

Are these wipers equipped with rain-sensing technology?

Unless the rain-sensing infrared beam signals the unit in the mirror base that water is on the windshield, the delayed cycle selected by the rotation of the stalk switch is not restarted.

Unless you’re in a dry location, the only way to tell if the rain-sensing wipers are activated is if they swipe once when the car is first started.

Start the car with the delay set to a short wait time and pour some water on the region of the windshield where the problem is occurring.

In addition, make certain that the region is free of road oils.

Because it does not wipe cleanly in the detecting region, the streaking might cause the wipers to run continuously. Thank you very much! Grime has gotten in the way of the sensor. I was under the impression that I would have to replace the entire switch arm._

Nissan Pulsar Intermittent Wiper Relay Repaired

Customer brought in her Nissan Pulsar with the complaint of intermittent wipers not functioning as well as wipers not “parking” – returning to the bottom position of the windscreen – and I was able to diagnose and resolve the issue. Always begin with the fundamentals – fuses. Then I realized that the circuit only had one fuse to run the system, so if at least part of the wipers were working (and all of the speeds were operating well), I figured the fuse must be in working order. After thoroughly investigating the system’s functionality, I discovered what is known as a wiper amplifier.

This may be modified by altering the resistance of the wiper stalk, which is controlled by a potentiometer.

This is what it looked like when it was removed.

I thoroughly checked all of the solder junctions and was able to identify the problem very immediately.

After looking at them under my digital microscope, I was able to plainly determine where the pins were not making touch with one another.

Once the system was back up and running, it was a simple matter of doing a repair.

In some cases, receiving a “thank you” from a client is equally as rewarding to receive as it is to complete a good repair.
