Wiper Problem on a 97

[Bravada 97]

This has to do with my Bravada but I thought I would post it here as it is similar to a Blazer and this forum gets much more traffic.

Here is the link to my thread in the Bravada forum:

Thanks for any help as it is greatly appreciated.

I did do a search and read plenty of posts about the faulty washer circuit board. I removed it, examined it and all of the solder joints were fine. The circuit board was in excellent shape. After reinstalling it I found that by wiggling the wired plug that goes into the circuit board that this will cause the wipers to stop working. It seems that there must be a bad connection between the plug and the circuit board or possibly at the end of the wires right before they attach to the plug in.

Since I ruled out the possibility of it being a circuit board problem I was wondering if anyone else has had a problem with the plug attachment and were they able to repair it without too much difficulty?

I would not know i just said search after reading through ur thread because i did not know if you did that on blaZer board or not.Did not mean to come off rude

There have been plenty of times that the circuit board looked perfectly OK, but it was bad. This happened to me and a few - well, to be honest, almost everybody I know that owns a Chevy. The solder joints weren't the problem, it was the components on the board itself. Wiggling the plug may be jump-starting the wipers, just like pulling on the wipers themselves could work for me, but given the track record of the circuit boards it's still very likely that the board is the problem.

Making a living dealing with and troubleshooting auto electronics, I can say that wires and harnesses (plugs) are usually the most blamed but the least likely to be faulty components in an electrical system. The reason most people like to think that a problem is "just a loose wire" or "just a bad plug" is becasue that seems like an easier/cheaper fix than a defective component - that's where they want the problem to lie, so that's where they make themselves believe the problem lies.

Replace your pulse board on the wiper motor housing. Because you wiggle the wires and it starts, you have the typical "finger failure"
on the circuit board. GM had a "special notice" recall that ran from
Feb '03 to Feb '04 that addressed this specific problem. You're out of luck on having them replace the board, it's about $30.00 for a new one.

Thanks Mike. Just so I am not confusing things, the pulse board is the same thing as the circuit board that I previously removed to check for bad solder joints correct?

Yes, one and the same.

I had the same problem and I put the new board in and all is fine now. I had one of the electronic guys here at work check the boad and he said that it was bad. Why I don't know.
