98deville Posted April 25, 2010 Report Share Posted April 25, 2010 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 Link to comment Share on other sites More sharing options...
Ranger Posted April 26, 2010 Report Share Posted April 26, 2010 Have you checked for power to the door? Link to comment Share on other sites More sharing options...
98deville Posted April 27, 2010 Author Report Share Posted April 27, 2010 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.. Link to comment Share on other sites More sharing options...

Take it out again, use a multimeter and check for power coming to the switch. Link to comment Share on other sites More sharing options...
