GMC 2500 Pickup Problem Report
GMC 2500 Pickup Windshield Wipers May Fail Due to Faulty Wiper Motor Control Board
The windshield wipers may not work intermittently due to a faulty wiper motor control board. Our technicians tell us that lightly taping on the wiper motor when the fault occurs should temporarily get the wipers working again. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.
