Windshield Wiper Motor
An electric motor is what makes the wiper blades move back and forth. This happens as soon as you turn on your windshield wipers. The majority of cars have a single wiper motor that controls the wipers on the front of your car. When a car has a back window wiper, it will have a separate motor.
The front windshield wiper motor is generally located under the outside vent at the bottom of your windshield. It is what moves the linkage back and forth to the wiper transmissions. This causes the wiper arms to move.
The motors could fail and need to be replaced. Gerber Collision and Glass encourage you to replace the motor to get your wipers back up and running for the rainy season.
