What is the Windshield Wiper Module all about?

The windshield wiper module, also called the wiper governor module or control module depending on the automaker, is responsible for controlling and coordinating all the various functions. It’s generally located inside the dash, mounted several inches above the accelerator pedal (the actual mounting location will vary depending on the make and model). It’s a miniature computer that’s responsible for managing the operation of the entire system, from the wiper switch on the steering column to the operation of the windshield wiper gearbox.

When the wiper switch position is changed, whether from off to on, or from one speed to another, a signal is sent from the switch to the windshield wiper module. The control module interprets that input signal and sends an output signal to the windshield wiper motor. When the wiper module is not working as designed, the wipers may not work when commanded, may not shut off, and may not work at the designated speed. The wipers can also start acting on their own volition with no input.

Keep in mind:

  • There is no routine maintenance or service for the windshield wiper module.
  • The windshield wiper module is located in a hard-to-reach spot under the dash, and should be replaced by a professional mechanic.
  • Other problems can mimic symptoms of control module failure including a faulty wiper switch or wiper motor relay.

How it's done:

  • The wiper motor is removed from front cowl
  • The defective wiper module is removed from the wiper motor
  • The new wiper module is connected to the wiper motor
  • The wiper motor is reinstalled onto the cowl
  • The wipers are tested to work properly in all control positions

Our recommendation:

Windshield wiper module failure is not common, though as an electrical component, it can fail without warning. Other problems should be considered prior to investigating the module itself, including relay failure, motor failure, a damaged gearbox, and a failed wiper switch. One of our expert mechanics will inspect the system and replace the windshield wiper module if required.

What common symptoms indicate you may need to replace the Windshield Wiper Module?

  • Windshield wipers operate inconsistently
  • Windshield wipers don’t work at all
  • Wipers initiate without input from the wiper switch
  • Windshield wiper speed cannot be controlled or changed

How important is this service?

Your windshield wipers are an important part of your vehicle and enhance safety by ensuring that you have a clear view of the road. If the windshield wiper module fails, your safety can be compromised. It should be repaired as soon as possible.
