have any of you had your wipers stop working or just work a little bit??

 

Yes, on my s10


was the wiper control board

 

When I got my ‘92 out of moms basement, fall of ‘20, it had been parked there since ‘97. I had to have the wiper board rebuilt. Capacitors we’re all blown on the board, inside the wiper motor. These (wiper boards) are not replaceable. You will have to find an electronics guy to help you. There are threads here about this issue. Wipers would work on low only and wouldn’t park themselves…they stayed up on the windshield. I would have to turn the key off to get them to stop moving. All fixed now. Electronics guy told me that the capacitors on the board were underrated for the duty they were performing. He soldered in larger capacitors and insured me I would have no other problems. So far, so good.

 

yes i have heard of control bd issues,, but thats not it....

 

that;s interesting.... i have taken the bd out but not there,,, i have heard of relays going bad,,,, my wipers worked then they did not,,,,, they now work so that the blades go up about two or three inches and come back down i can make them go faster but thats it relqays???? i dont know ......weird

 

From your description I'd suspect the so called "parking switch" to be not making contact. I don't think it's the capacitors because they wouldn't cause the failure you describe, they are involved in the delay function only. Here is a thread where I replaced my capacitors, just for anyone curious as to what's involved in that......
