Is it possible to break a driver side manual mirror control when replacing a window motor. I think that's what happened to my car when they tried to get the panel off.
Window motor replacement with a twist.. on 1997 Saturn SC2
The first step in the instructions for removal and replacement of the window motor is to remove the trim panel at the front top corner of the door where the adjuster is for the mirror. I think a small grub screw locates the adjuster knob in thee triangular plastic trim panel, perhaps the screw was not reinstalled properly.
