On my 03 1500 I have no function of the window, door lock, or mirror. The mirror heater does work but nothing else. Took it to the dealer twice. First time they said it was a broken wire. The second time they said I needed a new door control module. My son in law said it probably is the window motor. Question is could the window motor cause everything not to function? Have power going to the module and nothing works from the drivers side as well. Any help would be great.
