GM-GMC: No power on passenger door., gmc sierra, window locks

Question
I have a 2003 GMC Sierra,I lost all power to passenger door heated seats,mirror,window,locks,and keyless entry. I thought it was a fuse but couldn't find any bad.

Answer
It is not uncommon for those door modules to have programming issues.  You can try unhooking the battery and leaving it off overnight.  Reconnect and see if things work.  Short of that you will likely need to have the door modules reprogrammed.  In rare cases they have to be replaced, nine times out of ten a reprogram will fix it though.
Hope this helps
