Good point tech. There is a recall for '04-early '06 kingcabs due to the wire covering between the cab and the door. The wires may have shorted and caused a problem in your system. Your dealer can let you know if yours is included. You can check yourself and see if the covering over the rear door wires is split and see if any of the wires have broken.tech12volt said:Also the king cabs have wiring problems in the rear doors as well.
