Common signs include wiper blades that move slower than programmed, only have one speed, do not move at all, and don’t park in the correct position.
If you can’t see the road, it’s virtually impossible to safely operate a vehicle. The windshield wipers are specifically engineered to help clear rain, snow, dirt, and other debris from the windshield. Each wiper system is unique for every vehicle, manufactured for maximum efficiency and in many cases to improve the vehicle’s aesthetics. If the wiper blades are the arms and hands of your car’s wiper system, the wiper motor would definitely be the heart.
In order to move back and forth across the windshield, the windshield wipers are controlled by the windshield motor. When you activate the windshield switch on your turn signal indicator or other control arm next to your steering wheel, it sends a signal to the motor and operates the wipers at different speeds and duration. When the wiper blades don’t move after turning on the switch, it’s often caused by a malfunction in the wiper motor.
Although the likelihood of having a problem with your windshield wiper motor is rare, there are a few warning signs that will alert you that the wiper motor is damaged and needs to be replaced.
