Windshield Wipers May Fail Due to Faulty Wiper Motor Control Board on GMC Suburban 1500

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.

problem details
1998 GMC Suburban 1500 160,000 mi,
The windshield wipers will not work or will work intermittently. They have not been fixed. We heard that it might be a recall item.
Wipers not responding or have a mind of their own. Also our light switch is now defective
Wipers, once turned on will run after being turned off, or the truck motor is turned off. Sometimes this time lag is 10-15 minutes. Wipers also fail to respond to variable speed settings and delay settings.
