Windshield Wipers May Fail Due to Faulty Wiper Motor Control Board on Chevrolet 2500 Pickup

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.

my windshield wippers will work only part time. somedays i turn on the truck and they work fine and other they dont work at all. sometimes they work when i first start the truck but will stop working after a few miles of travel.....unreliable....not fixed yet

wipers only work when they want to it's usually only when it's not raining. back brakes lock up usually after it rains and i have to throw it in neutral and push in the clutch and brake 3 to 4 times to unlock them and to get them to stop making a screeching sound.

Mine do the same thing. I took a zip tie and pulled the plug in to the board up to make a better connection and it seems to work for now
