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

Problem Description and Possible Solution

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.

Windshield wipers would stop working intermittently. Required tapping on the wiper motor box to restart, and sometimes even that failed.
Windshield wipers work,problem is when i turn them off,they stop in the middle of the windshield.
I then have to turn them on full blast to get them down all the way..
