93 gmc windshield wiper problem Sign In

Hello I have a 1993 gmc s15 Sonoma and I have an electrical probolem. When I turn on the windshield wipers it blows the fuse. The fuse dosent blow until I turn them on I have tried many fuses and it blows them all so I am pretty sure I have a short I just have no idea where. The motor looks like it was replaced with a rm one I just got the truck so I'm not sure. I don't want to just buy a new motor if thats not it. I was wondering if you guys could tell me where it might be or recomend some tests I do have a multimeter and basic electrical knowledge. Everything else on the truck works and has never blown a fuse. I would apreciate any help you guys could offer.

Finding shorts can be difficult, even for a skilled technician. First thing is to eliminate the motor itself as the cause by unplugging it. See if it still blows the fuse with the motor unplugged.


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
