2003 Avalanche door electrical, remote locks problem?

I have an 2003 Avalanche - it lost all power to the front passenger door, nothing in the door works, window, mirrow, locks, light, also at the same time the remotes will not lock or unlock any of the doors.  I checked fuses, and as much of the wiring as I could get to.
Any help or ideas would be appreciated.  email to ejkkj@hotmail.com  Thanks much.
