Anybody have experience messing around with the driver door wiring harness? I have a 2004 XC90 2.5t. everything on the driver's door won't work intermittently. (Mirror, lock window) The switch panel will control all the windows and locks on all the other doors but for some reason won't work on the driver's door. I will do something like jiggle the gray connector on the switch box and then the window and lock will work for a while, then there will be a small fast clicking/buzzing noise coming from the switch panel, and then everything in the driver's door will stop working. My guess is it's a power or ground connection somewhere to the driver's door? Maybe in that gray connector? Anyways, if anybody has any experience with that switch panel or know of a wiring diagram, I'd be grateful.

 

How about a bad drivers door module - it's the one that is used the most.
