wipers make a grinding noise when operating what do I do?
The grinding noise might be coming from worn gears in the wiper motor transmission. If it is, replacing the wiper motor is the only fix.
Thanx Tester I will look into getting a wiper motor.
Is it noisy when wet? If it is only noisy when you drive in a mist with the wiper dragging across the dry glass it may be the blades.
