I bought the car with many little issues, and tackled the floppy door panels/switches today. Got the panels secured temporarily (prev owner had broken off all but 2 clips and tried to glue window switch panels) and would like to fix the pass window before buying/installing the new panels. It operates correctly with the switch, but clunks and doesn't move without help pulling it up/down. Sounds like a gear jumping teeth, believe it or not...?? Hopefully one of y'all may know the trick as I surely know very little about this. Thank you!
