Windshield Wipers May Fail Due to Faulty Wiper Motor Control Board on Cadillac Escalade

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 started when trying to spray and clean and stopped about a quarter way up. Now they are stuck there.
With the amount of rain in Oregon, this problem was easy to watch progress. It started slowly, over time. At first, it was in only one position on the intermittent wipe, then it went to more positions. Now, it will run at wide open continuous wiping on the lowest intermittent setting, switching to off on it's own, then if the switch is moved, it might switch to slow continuous, or whatever it decides. I bought the extended warranty when I purchased the car in 2013, so I had a local GM dealership look at it. They said they replaced the rain sensor by the windshield, and hoped that would take care of it. That was in the middle of the summer, so no testing happened. Now, the worse the rains, the worse the problem. Now, I find out, that since the ice, the windshield got broken, and has to be replaced. Turns out that the rain sensor is IN THE WINDSHIELD, not by it, and they didn't replace the windshield, so I'm sure the problem is in the board in the motor.
