@jamesmackin here is how to check it
On the power window master switch connector Connect terminals No. 18 (or No. 17) and No. 20, and terminals No. 17 (or No. 18) and No. 16 with jumper wires.
Check right rear power window motor operation:
The right rear power window should close (or open).
Should that not work you know you have
- Faulty right rear power window motor
- Faulty right rear power window switch (You already ruled this out)
- An open or high resistance in the wire
Here is how to check the motor
Since you already replaced the regulator etc. you probably do not need instructions on how to get into the door :-)
@jamesmackin so you checked the master switch connector and have no power for the read window? Or did you just check at the door? You will need to check at the main connector. Check the under the dash fuse panel. I believe that your windows each have an individual fuse #43 is for the rear passenger side power window.
