Ok wife's van, G20 Mark3 conversion, wipers quit last night.<br />She went to turn them on and they would not come on.<br />Checked fuse and replaced with new(was not blown) and still nothing.<br />My question is, do the wipers have a circuit breaker also or share one with something else?<br />Thanks in advance as always.

Want to try something?? Check the mounting bolts that hold the motor to the firewall. On some, you'll see a ground strap spot welded to one of the washers going to the chassis. Loosen and re-torque these mounting bolts. The bolts sometimes pass thru rubber mounting bushings. I repaired a friends wiper motor on a Chev Astro. Seems under the 'black box' controller mounted to the motor itself had developed bad solder joints on the major brass feed-thru's of the PCB. Re-heating the connections and applying fresh solder fixed him up.

What year is it. Some of the mid 90's models had a recall on the wiper motor. The controller was bad. It is the black box that mounts on the motor itself. Sometimes wiggling it around would help temporarily.

wvit100, it's a '92 model with low miles(68,000) and never has had a moments problem out of it.<br />I checked alldata and found no recalls for the wipers.

Re: GM gurus

I have a '97 GMC pickup and I have received a recall notice about the wipers. If I could find it again I'd take mine to get them serviced. I've owned the truck about 18 months and a couple of times the wipers failed to operate. I usually reach out, grab the wiper arm, and give it a little tug. Sort of a "kick start". They've always started operating.<br /><br />It's funny, the only time they don't work is when it is raining.

Re: GM gurus

Hi SBN<br />The guys are on the right track. . .<br /><br />The circuit board on the motor has cracks in the solder joints. Remove it with a few screws and resolder the obvious ones. Typically the ones closest to the plug. . .

Re: GM gurus

Schematic is correct. I cant tell you how many iv re-soldered.
