bad ground. check the ground on the motor that goes to the body.

I wouldn't rule out cold solder joints either. Gonna have to own a soldering iron, solder sucker/solder wick and the know how to use them though... Repaired the board on my 1994 C1500 daily driver and my coworkers 1996 S10 and that fixed the problem. GM has had a problem with this for years.
This will make the folks who still have dial up happy
. Sorry but it's the only way to see what a cold solder joint looks like:
This is what the wiper board looked like on my C1500 when I took it out back in April of this year. If you look at the rectangular joints at the top of the board, you can see how they are "cracked" around where the pins for the socket come through the board. This is caused by bad soldering technique. And the effected component(s) will act like they are not even connected to the circuit when it happens... In this case, those are the pins that connect the plug on the wiper motor to the wiring harness. It is VERY easy to overlook unless you have worked in electronics before and know what to look for.

Yup. A new wiper motor for my truck is around $55. A new one for my coworkers S10 is around $70. Repaired both of them with probably what amounted to a pennys worth of solder
. GM has had a problem with this for YEARS affecting hundreds of thousands of vehicles. So much so, it is the second thing that I suspect after a blown fuse if the wiper motor is inop. If you do a search for "GM, cold solder joints" and you will see what I mean

Plus, you saved your original part. You said 1994 truck. The board was mfg/inspected on Dec 21, 1993, 2nd shift. The "numbers match"

That is not the proper way to fix it because the old solder has degraded from age and oxidation. While you *could* just reheat the joint, it will not be as strong as a joint made with virgin solder. Besides, solder is cheap

turn the wipers on and manually move the wipers back and forth, i did this and mine started working again, i believe it is the circuts in the wiper motor. mine have been working fine after doing this but may need to be replaced at some point

Is that board inside the wiper motor then ?

Re: Wipers and winshield squirters are dead?? What could this be?
I found this thread on a search. My wipers stopped working a few days ago. Thanks to the suggestions in this thread I found the problem: a bad ground.
Finding the problem was actually simple once got an idea of what I was looking for. I attached my test wire (a wire with an alligator clip on both ends) to the copper strip that the wiper motor uses as a ground and the other end to a bolt in the firewall. Then I tried my wipers and they worked. I just added an extra ground wire after that.
Thank you for the suggestions guys.
