What is a windshield wiper motor?
The windshield wiper motor is a small, electric motor with a shaft that connects to the transmission assembly. The transmission assembly converts the rotating movement of the shaft into a back-and-forth or linear movement for the windshield wipers.
Some hatchbacks, station wagons, SUVs, and vans have another wiper on their tailgate, in addition to the wipers on the front windshield, to keep the rear window clear.
What are the symptoms of a bad windshield wiper motor?
If your windshield wipers make grinding or clunking sounds, operate slowly or erratically, won’t park in the down position, or the windshield wiper blades stop working altogether, it’s probably time to replace the windshield wiper motor.
How often should a windshield wiper motor be replaced?
Windshield wiper motors are designed to last the lifetime of your vehicle. Wear and tear can shorten that lifetime, however, and some experts recommend getting your windshield wiper motor replaced every ten years or so.
Can I replace my windshield wiper motor myself?
The general consensus is that replacing your windshield wiper motor isn’t particularly difficult, and can be done using basic tools. But if you have little experience with DIY car repairs, you may want to leave the job up to the professionals.
