What are the gears made of?

BEST ANSWER: A slightly flexible thermoplastic or nylon. I've had no problems after replacing mine. I also had the issue of one headlight not raising sometimes that finally stopped raising at all. That turned out to be cracked solder joints inside the headlight control module. Not a tough fix if you (or someone you know) can solder.
