The windshield wiper motor supplies the motion to operate the windshield wipers. It also includes a sensor that helps “park” the wipers in the proper position when they are turned off.
Symptoms of Wear or Failure
- Wipers may only work at one speed, not at all, or only intermittently
- Wipers may stop in the middle of the windshield when turned off
Related Repair Advice
- During replacement, a quality shop will inspect, lubricate, and torque all of the components of the wiper linkage. Adjustment of the wiper arms and replacement of the wiper blades may also be necessary.
- The wiper control switch, wiper control unit, wiring, or broken linkage components can all behave like a failed wiper motor. Failure to properly inspect these items during the diagnosis may lead to the unnecessary replacement of the wiper motor.
