Vehicle - 2003 GMC 1500 HD (Crew Cab) Sierra, 6.0 L Gas, 70K miles.
I have a list of electrical components that quit working simultaneously.
Front Passenger Door:
Mirror Adjust Functions
Other items that are inoperative:
Retained Accessory Power (RAP)
Door locks & window lock-out on driver door module
Power mirror fold, both sides
Things I've tried:
All fuses checked and found to be ok.
Disconnected battery for several minutes.
Pulled most relays and accessible circuit breakers.
It seems to me that this list of problems tends to rule out a single component other than the BCM (unless there is a hidden fuse/cb/relay that powers the right bussed connection box).
I have an aftermarket repair manual that leaves me a little dumbfounded.
Can you also address the following questions:
Can't locate fuse, in any, to right bussed connector box.
Can't locate relay, if any, for RAP.
Unsure of BCM location.
Any help would be appreciated.
have the same problem?
