The thing to do first is have the vehicle hooked up to a professional grade scan tool an have it checked for DTC'S in the driver door module , an to see if the scan tool will talk with the module !
Then if no codes are present check for battery power an good grounds at the module ! You have to take the door panel off the door to get at the module . I have one of these modules out in my tool box , I got it at the auto salvage yard . $10.00
In order to control window operations, as well as other door functions, door modules must be powered up. Battery voltage is supplied by the rear fuse block, through separate circuits, to each door module. Each door module is separately grounded through a ground stake. Additionally, the door modules use these power and ground supplies to provide voltage and ground to their associated window switch, and to provide voltage and ground for door lock operations. The front door modules also use these power and ground supplies to power the window express up sensors, and for outside rearview mirror operation .
