Body Control Module -2003 GMC 1500HD. Anybody know about troubleshooting changing BCM

[motfu]

My last thread received no replies, so I'll try it from a different angle.

I have a list of electrical components that quit working. They are:
Front Passenger Door:
Power Window
Power Lock
Mirror Adjust Functions

Other related items that are inoperative:
Keyless entry
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.

Can't locate fuse to right bussed connections.
Can't locate relay for RAP.
Unsure of BCM location.

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 that powers the right bussed connection box).

Anybody have any ideas for me?
