1993 Chevy 3500 Truck, winshield wipers stop or don't come on sometimes. Can grab the blade and move, and they start up again. Replace wiper motor?
No,you dont have to.This is a common problem I have seen many times.If you open the hood and locate the wiper motor on the fire wall,it will have a black plastic cover mounted with 3 torx bit screws and a wire connector on the left.This is the wiper control module,it will need replacing.Note:you will need to know if it has intermittant wipers or not,and it should be available from most parts houses.Hope I have been of some help,Marc
