1982-86 Firebird use a 3 wire motor that isn't compatible with yours. You'll need a 1987-92 Firebird headlight actuator motor. Does your motor spin, yet the headlight door fails to raise? If so, then you don't NEED to replace the headlight actuation motor. The problem can easily be cured using the TDS p/n 207280 headlight repair kit or the TDS p/n 209280 Deluxe Headlight Repair Kit. Hers's what has happened: There are 3 solid gel bushings inside the large nylon gear that is driven by the worm-drive of the motor. These bushings transfer the load from the gear to a 3-lobe cast hub that is part of the actuator shaft. These inserts harden and crumble with age, breaking down to roughly a spoonful of crumbs. At this point the gear will no longer turn the hub to raise and lower the headlight assembly. Instead hub will just free wheel on the gear. Replace the bushings with the solid Delrin bushings from my kits and your headlight motors will work better than new.
