1500 HD passenger door electrical problems

[motfu]

2003 Sierra 1500 HD - passenger door electrical components (lock, window, mirror) are inoperative. Keyless entry, mirror fold function, Retained Accessory Power (RAP), and window/door lockout switch are also inoperative.

I know from other forums that this is a fairly common problem. However, those forums did not provide a good solution. Some solved by disconnecting battery/fuses/relays (supposedly to reset the body control module/truck body controller). That didn't work for all. Others replaced the BCM/TBC but I'm not sure if that fixed their problems.

I have check all fuses. All good.

I could not locate the RAP relay or 50A fuse. Does anyone know where they are?

Does anyone know if these are symptoms of a malfunctioning BCM/TBC?

Any help would be appreciated.

Vehicle details - 2003 GMC Sierra 1500 HD, 6.0 L, Automatic Tranny, center console, towing package.

Did you ever figure out this issue with the passenger door electrical and keyless remote not working. I have the same problem with my 2007 Sierra pick up. The window is down and it's now raining.

Thanks,
