Other than Mitchell, who prints wiring diagrams for individual vehicles. I know Chilton's used to, but they were more generic than for a specific vehicle. I'd like to find out what these wires are for.
I also would like to fix an intermittent radio problem on a 2002 GMC Envoy. Seems this is a "known" problem that GMC can't figure out. I have seen two postings on this problem and each required the replacement of the radio.
Dash display shows all is good, volume bars move, tuning OK, just no sound from speakers. If the fault is there when you shut off the car, it drains the battery. Unique shut down procedure to check radio is working before parking for the night.
Thanks again for all your help.
