checked all of the wiring... its all fine... I just dont get it... rear windows AND the sliding rear window... fuses all ok, new drivers door master switch didn't fix it.. WTF? Any more ideas?
Did you actually check for continuity between the wires in the door conduit and any of the inop components or just visually inspect them?
I don't have access to tech info for your truck year/model, but for a new 2500 it says they are all powered by the BCM. Here's an excerpt from the Rear Power sliding window operation; the power windows are similarly worded:
"Rear Power Window Switch - Operation
OPERATION
The power sliding rear window center pane of glass is driven (slides) via cables through a 2-way window motor regulator. A bi-directional switch is used to control the sliding glass which is located in the overhead console. Sliding the switch one way will operate the power sliding window pane open. Sliding the switch back will close the power sliding window pane. The pane must be unlocked in order for the power feature to function.
The switch is supplied power by the BCM. The overhead console switches, bulb holders and wiring harness are serviced only as a unit and are not available individually for service."
It may be worth your while to spend the $20 for access to tech info on your truck at alldatadiy.com. I've used them for years and it has saved me many hours of troubleshooting and thousands of dollars in misdiagnosed issues. Love it.
