Without a schematic I can only speculate, but I would suspect the console switch. Often the switches are wired together. For example on my Toyota the passenger window stopped working but the cause was the drivers switch for the passenger window. You could possibly check for voltage at the door switch. If it is not there then it cannot pass it along. Did you try searching? Your car is different than mine so I can't really say more. The system changed to CAN bus in '98.
