[Ski-me]

I take the cable off of the motor and then put my drill onto the end of the cable. Start slowly to be sure you are spinning the right way, and then you can run the window out (supporting it as mentioned above).

Once the glass is out of the way, I think the panel is attached with little nuts on the inner part of tailgate. The panel itself has threaded studs attached to it that go into the tailgate sheet metal, then bolted together with nuts.

If I'm lucky, it might be a 10MM socket.
