Fixing Corvette C4 1984 to 1987 headlight motor (not the gears)

A really shitty instruction video I made trying to learn to make movies with Kdenlive. I apologize for speaking bad english and mumbling alot but the video shows a common problem with headlight motors that I could not find any solution for elsewhere. I hope it helps someone. I promise that the next one will be better.

Other possible problems with the motors can be:

1. Broken plastic gears (motor spinning), buy a repair kit.
2. Broken control relay, swap left/right relay to see if the problem changes sides.
3. Oxide or crap in motor, clean brushes, collector, switches with wet sanding paper (aluminum oxide type).

If you want to support the channel, please send me a knob for my headlight switch.
