OK...Got it done!! Thanks so much for the advice. The door panel was the easy part. The motor on the window regulator was only running in one direction (down) and the guide sleeve for the regulator arm was broken (nylon). I took the pragmatic approach and used two wooden dowel rods to place in the window tracks to keep the window up. I removed the regulator and will fix it/replace it later. For now, at least, I have a window that stays up and it not covered in duck-tape to keep the rain out.
Thanks again for the great advice!!
