Pontiac Firebird Problem
Average Mileage: 99,909 mi (20,000 mi - 200,000 mi)
I have had to replace both sides 3 times as the actuator motor gears are made of plastic and not metal. Each side cost a total of $300 and $85 an hour labor X 3 hours.

heard the sound of a motor on passenger side after closing the headlights. Found it to be the headlight actuator. Hope I don't need one for the drivers side given the pricey repair.
