The best suspect is broken wires between the driver's door hinges. What have you tested so far, and what were the results?

Power at the door module, and the BCM under the dash behind the glove compartment. It has no windows, door locks, mirror adjustment. Finally got the drivers seat out removed the covers that cover the wiring from the rear to the front, all seems good no corrosion in the harness area at all under the seat.

There are three orange wires at the driver's door module. Check for twelve volts on all of them. If it is missing on terminal "A", check for a defective thirty amp "power window" circuit breaker in the fuse box cleverly hidden under the back seat. If it is missing on terminal "A8", check the "DMV MDL" ten amp fuse, also under the back seat. If both of those are okay, but you do not have twelve volts on terminal "A7", suspect that module. I am sorry that I do not have a drawing of the plugs.

Can you figure out which terminal that is? Two orange wires get 12 volts through two different fuses. The third one takes that 12 volts to the switch assembly.
