![]() The windshield wipers are a not a convenience they are needed for safe operation of any vehicle. In this situation, you'll have to contact a local ASE certified mechanic to replace the module as this issue can't be repaired. This is typically caused by an internal circuit inside the wiper module that sends a power signal to the wiper motor, but not a duration indicator. You'll be able to hear an electric signal coming from under your dashboard which is the wiper motor, but the wiper blades are not moving as they are directed.

There are several settings on the switch ranging from speed to interval time. The wiper module also sends a signal from the switch on your signal arm or steering wheel to the motor to move the blades. If you notice that your wiper blades don't work after you've turned on the switch or activated them, or if they won't stop moving across your windshield, it’s a good idea to contact a local ASE certified mechanic as soon as possible to properly diagnose the exact cause and repair the issue.

Some mechanics refer to the wiper module as the wiper governor module. The entire system is controlled by a windshield wiper module. 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. Just like any other mechanical component, it is susceptible to wear and tear and can break from time to time. However, a tiny device known as the windshield wiper module is the real hero that really allows all of these individual components to work effectively. Most of us associate mechanical units like the windshield wiper blades, arm, and motor as being the most important elements for keeping the windshield clean.
