Rear Window Fixed!
Thanks to all the members of this forum for the tips, tricks and trouble shooting advice! You all have been an enormous help in diagnosing the rear window issue. I was able to successfully repair my rear window/wiper/defrost. Here's what worked for me:
As mentioned in my comments above I had tried every troubleshooting technique mentioned in this forum with no success. I was at the point of attempting to disassemble the motor and replacing the brushes as suggested by
hurron, figured I had nothing to lose because in my mind the motor was bad and would need a new one anyway.
I read the service bulletin that tells us to remove the regulator to replace the motor. This is NOT necessary. I got to looking at the rear window motor and noticed that it is held in place with only three bolts from behind. Using a mirror I determined the bolts were a T25 torx head and using a 1/4 boxed end wrench with T25 torx bit in the wrench I was able to break them free I then backed them out with a 1/4" drive ratchet with the T25 torx bit in a 1/4" socket. Once these bolts are removed the motor falls free.
With the motor dangling from its harness I decided to give it one last try and to my surprise when disconnected from the regulator it spun free. My motor was good after all!
The window would still not move, I had to go inside for a while so I tucked everything inside the door shut it, when I lightly slammed the door shut the window moved freely. I found a piece of the rubber gasket sealing the window had become dislodged an was partially obstructing the window's channel. I'm guessing that was just enough resistance to keep the window from operating. Perhaps there was something else that was in a bind but I didn't notice it.
Reseated the gasket, reinstalled the motor opposite the way in which it was removed, tested, reset auto switch by holding each direction for a couple seconds and window it ran perfect as did the wiper and defrost!
Attached are a couple images for reference, let me know if anyone has any questions about the procedure I used.
Thanks Again! Great Thread!
