Key switch, remote and power window switch won't lower rear window. But rear window will lower if connected directly to -12V. Rear wiper is possessed. Turns on and off from the driver control but stops anyplace it likes. Shaft is bent and the splines are stripped so I've been testing it with the wiper arm off. I ordered a new wiper motor and arm but I don't feel confident I can get the window to go down with the controls.

Hi,

The window motor sounds good. So, the first thing I need you to check is to make sure the ground is good. I attached a pic from the wiring schematic which indicates two locations to check. Do this first and let me know what you find. (See Picture 1)

Here are a couple links you may find helpful:
