GMC Troubleshooting Questions? Ask a Mechanic for Answers
It sounds like the passenger door switch is the culprit. The window wont work with the driver's switch because it actually uses the relays inside the passenger switch to make the window motor operate. It isnt the regulator if you tried to plug in the motor and it didnt work. Replace that passenger window switch and you'll be back in business.
That's what I thought the culprit was I ordered the switch already but just needed an expert opinion to confirm that, because I wasn't sure where the relay was located so Thanks.
I tried replacing the switch it still doesn't work, any suggestions?
Can I use a votymeter to do this test?
did you test both black wires?
Both got light
Yeah you got that right, it seems the electronic stuff cannot be trusted you never know until you get the part. I gues a costly lesson if they don't own up. Thanks again I'll keep you posted on the new switch. Thanks again.
