It just stop working all of sudden one night -
Answer 1
It could be several things but would need to start to diagnose the problem by looking at a wiring diagram. It could be a fuse, a damage harness going out to the door or a bad master switch. At the battery fuse box check fuse #1, 20Amp and fuse #2, 15 Amp in the main fuse box. White/violet and door lock switch should have power if fuses and wiring are good to that point. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect....
