My 03 H2 lost all power on the passenger side front door, no remote lock, mirrors, heated seat, or windows. I checked the DDM and the PDM and they all look fine, fuses look great too.

Anyone know what to do to solve thise issue?

 

Check the harness where it goes through the flexible rubber piece between the door and the body on the passenger door. Common location to have a wire eventually break. (Probably more likely to be in the driver door rubber piece, is that door gets open and closed more often. You'll probably need to double check the wiring schematic, but I suspect power to the other doors goes through the driver door module.)
