Guys, I need some help. I have an '03 sierra 2500hd, lb7. The issue is that when I turn on my wipers, I cant turn them back off. When I put them on int. they go to regular speed. I can switch to high speed, but cant get the buggers to turn off unless I shut the truck off for like an hour.
Please help me, Im to cheap to go to a shop, so I really need help!
Thanks in advance.

sounds to me like your intermittent module went bad. just had one go bad on a chevy van.

Either module or a bad ground.

On a '95 Astro I was at the dealer and they asked me if I wanted a new pulse/wiper module, FREE !, GMC Envoys and a BUNCH of others were going bad too soon so there was a servce bulletin on the part, mine were working fine but I said sure why not,

On my '94 Blazer the wipers would stop in mid-stroke, and not go off when I wanted, then stop when they decided to, I got a new module from one of the cheap parts places, $21.95 and they work perfect now. easy install,
Manuel

I called the Chevy house and they said that module was $112.00! Does anyone know where to get one cheaper than that?
