Intermittently Windshield wipers not working

Had the same problem, turned out to be the pulse board in the wiper motor.

Two wheel drive automatic

the heater, power windows, radio and wipers all stopped working. What could cause this?

I found it. It was as simple as changing a fusible link.

The windshield wipers do not work. Has a slight buzz sound when turning them on. Sometimes they go on when I hit a bump on the road. Could it be circuit, motor, or wiper control module? Help! Could this be a recall?

I have a 1995 gmc Sierra and it did not that I had to replace the module. Mine was under recall check with your dealer or manufacturer.

I Believe you probably had a recall on the wiper motor. My 1995 did, but I was on vacation when my wipers stopped working. Did not know about the recall then. The problem is a lot of cold solder joints in the wiper motor assembly circuit board. I just retouched a soldering iron to all of them and it has been working for years. It was very obvious all the cold solder joint when you looked at it. Take it to the dealer and ask about the recall on them.
