Windshield wiper stopped working

Sounds like the wiper motor control board failure. Common problem on some GM vehicles. BUT GM says it's only on certain ones.

Anyway. There are a couple screws that hold the board to the wiper motor. Remove them and the wiring connection. If you want to repair it yourself you need to clean and re-solder the wiring harness connector on the board. Then put it back on. Or you can buy an updated board at many FLAPS and just bolt it on. I also make a small wire hanger to hold the wiring harness up so the strain is off the connection.

I have windshield wipers that when activated while it is raining, will stop working. If I have them on delay they will function at the setting for a while, 4-5 minutes, then either quit or go into a longer delay.
I have had to wrap a piece of baling wire around the wireing harness and the wiper motor to try and keep it running but I still have to get out of the truck and wiggle it when the wiper action stops. I believe that there was a recall on this for 1996 models.
Have any better ideas than baling wire?

Your problem is the circuit board on the wiper motor and yes there was a recall. Call the dealer with your vin number and have them check to see if you qualify, if not then replace the circuit board. Very easy to do, 3 torx screw and pull it straight off, then plug the new one in.
