There are two"generations" of GM headlight door motors in the 82-92 era, including Fiero and Friebird. The later ones (abouty 1989 up) are a more robust design and use a separate controller for current regulation. The big problem I had with my first design using a Le Baron motor was the motor overdrove the doors, causing lots of stress on the mechanics.
If you're scrounging at the boneyard, be sure to get both motors, the controller on the firewall and the bolts that held the motors to the doors.
