Why do my windshield wiper blades move slower than normal?
If you activate the wiper switch to a fast speed or high setting and the wiper blades move slower than they should, it may be caused by a problem with the wiper motor. Sometimes the mechanical components inside the motor will be clogged with debris, grime, or other particles. If this happens, it can impact the speed of the motor.
What causes a wiper motor to go out?
Sometimes it can be caused by a blown fuse that operates the wiper motor. However, a fuse will only burn out if there is an electrical overload of power to that particular circuit.
Why is my intermittent wiper not working on my Jeep?
Since your wipers don´t go into low speed continuous mode, it seems that the rain sensing module is working, but not sending a wipe command. Check if the infrared sensors from the rain sensing module are clean and no obstacles are in their way (like a sticker or such). KYB Gas-a-Just shocks / Transgo reprogramming shiftkit. They work!

Are there any problems with the General Motors wipers?
General Motors also has problems with the pulse board module. I have witnessed several cases where an owner thought the wiper motor was bad, and replaced it, but the pbm had also went kaput at the same time. Most FLAPS (Friendly Local Auto Parts Stores) will stock them in new as well as remanufactured versions.
Why is my Wiper not working on my car?
If nothing works, an electrical problem could be the culprit, possibly a blown fuse. A bad fuse on its own doesn’t occur often, but occasionally, finding and changing a bad fuse can get your wipers working again. A word of caution: because you’re working with the wiper system, a blown fuse should be treated very carefully.
How does the motor work on a windshield wiper?
The windshield wiper blades don’t operate on their own but are just one part of a complete system. The windshield wiper motors are responsible for supplying power to the blades. When the motor works as it should, the blades move in a systematic, smooth motion.

How does the wiper arm work on a car?
When you activate your windshield wipers, electricity is sent to the wiper motor, which in turn activates the linkage, and then operates the wiper arm to move the wiper blades across the windshield. The entire system is controlled by a windshield wiper module. Some mechanics refer to the wiper module as the wiper governor module.
How to control the speed of a DC wiper motor?
Click to expand… Standard mehod to control a DC motor is PWM. You need a puls generator with variable pulswidth. A 555 timer will do this job. The pulses are used to switch a power transistor that controls the motor. a windshield wiper motor. The problem I’m having is that the motor turns to quickly in low speed!
Why are my windshield wiper blades not turning on?
Before it can control the speed or duration of the wiper blades, it must first tell the motor to turn them on or signal them to shut off. There are several specific problems that might cause the wiper blades to not activate, including the switch itself, the motor, the linkage, or the wiper arms.
What happens when a windshield wiper relay goes bad?
When the relay is faulty, the windshield wipers will only work at the same speed that the last relay signal was sent. In layman’s terms, if you had your windshield wipers on the slow speed the last time they were active, and you turn them on again under a different setting, the relay switch should send that updated information to the module.
How does the windshield wiper module work on a car?
The wiper module also sends a signal from the switch on your signal arm or steering wheel to the motor to move the blades. There are several settings on the switch ranging from speed to interval time.
What causes the intermittent wiper to stop working?
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. This can lead to a potentially unsafe driving situation as sometimes we encounter weather conditions that require the use of the intermittent switch.
What to do if your windshield wiper is not working?
Make sure that the link between the wipers and the wiper motor is not broken. Next, try tightening the bolt that holds the wiper arm in place. It is possible that there is a problem with the controller area network or the front signal acquisition module (SAM).
How are windshield wipers controlled by the motor?
In order to move back and forth across the windshield, the windshield wipers are controlled by the windshield motor. When you activate the windshield switch on your turn signal indicator or other control arm next to your steering wheel, it sends a signal to the motor and operates the wipers at different speeds and duration.
