I can't seem to get the rear window switches working. Both windows work from the master driver control, although a few times the left rear won't work from the master control.

I opened up the door panels and don't see anything immediately wrong. I bought a new switch from the dealer and tested it on both sides and it didn't fix the problem on either side.

Any suggestions on what the problem could be? I did notice in the maintenance logs that they replaced the rear window switches THREE TIMES. That's weird isn't it?

On a related note, the left year door lock doesn't unlock when pressing the driver unlock button. All 3 other doors unlock fine. I don't hear any clicking in the LR actuator. What's interesting is that I do hear the left rear actuator do something when I enable or disable child locks.

Probably its set up that way for police work. There should be an upfitters guide to get those switches working. Do a google search.

The upfitter said he thinks they are disabled from the factory in the computer.
