The rear drivers side window doesn't operate. Checking the connector to the switch and some experimentation, I determined no 12V to the connector, but the controlled ground (pin 4) operates correctly as verified by turning the driver power window "lock" switch on and off. The fuse for the rear window provides power to the LED's in the drivers switch, and the LED's work when the fuse is plugged in, so voltage is getting to that switch.
All of the other 3 power windows work.
If I hot wire 12V to the window switch CABLE for the driver/rear window, the power window operates correctly, so the problem is that the 12V to the power window connector for the driver/rear window isn't getting the 12V.
Checking the schematics, the 12V for this window goes from the fuse to the window switch and also the Power Window Control Unit (inside driver's door) and the Driver's Door Multiplex Control Unit. Because the drivers switch LED's operate correctly, the Multiplex Control Unit is getting the voltage. Probably the same for the other module since everything else works AFAIK.
This seems to be a wiring problem. I need to know WHERE the 12V line splits. Assuming that there is no problem with the cables themselves, the junction must occur at some connector. But where?
