SYMTOMS OF GEAR FAILURE:
1. The headlight motor runs for several seconds but does not open the headlight.
2. The headlight only opens partially or droops after it has opened.
3. The headlight opens and closes but the motor continues to run with a loud grinding noise.
Most headlight motors fail because of the plastic gears that GM put in these motors. The electrical part of the motor typically does not fail. I have also seen a lot of gear failures with the cheap undersized aftermarket plastic gears sold by others.
Unlike other low-quality plastic and brass kits, this kit contains all of the parts and lubricants needed to do it right the first time! This brass gear kit will last the lifetime of your car so you will never need to rebuild again due to a bad gear. This heavy-duty brass gear will never break or sheer teeth like the OEM plastic gears, and even lower quality aftermarket plastic gears being sold, and they will not bind up your motor like some of the low-quality brass and aluminum gears sold by others.
