left rear window and lock will not work?


Recommended Posts

I have a 2003 DTS and all other windows and locks work except for the left rear window and lock. I tried switching the master front switch with another and it still will not work. I also switched the rear door module and still nothing. I also checked all the fuses and couldnt find a bad one. Could it be a relay, maybe the wiring harness for that door? I'm stuck need help

Have you checked for power to the door?

From the wires? No, How can I go about doing this? Could that be a possibility, that the wiring harness is bad for that door? The only thing that seems to work on that door is the speaker..

Evidently you know how to take the switch out...

Take it out again, use a multimeter and check for power coming to the switch.
