The harness in the door plugs into connectors coming out of the frame. The harness running into the frame then runs down into another harness. Wiggling those harnesses is where the short seems to be, not in the harness in the door. That's alot of wire to check for a short. Does the power go to the driver side switch then to the passenger? I can't imagine why there would be an issue on the drivers side since it hasn't been touched but something is causing intermittent power along the light blue and light brown wire coming out of the vehicle frame.
