There'* a control module in the door that provides power & ground functions for the door locks, window motors, heated mirrors etc. The control module communicates with one or two other modules (ie drivers door, rear integration module,etc) via serial data buses. Check the fuses in the rear fuse block for the windows, locks etc. In all likelyhood they are probably not blown. There may be a connector loose or a faulted module or something simple. One time the Driver Info Center in my dash went dark (switch module ) all functions on the DIC were inop. I popped the module out and found the connector just about ready to seperate. They never locked it in at the factory. Your Dealership techs should be able to localize this prob in short order.
