Yes, that is how they are made
It has a chain with a cam gear and crank gear.
the humming noise you are hearing is the gear inside of the headlight motor. there is a worm the motor turns, you chipped a tooth off of the motor. it won't read that the headlight is down, so it continues to turn until the override shuts it off. its a factory defect. Pontiac used a nylon motor to turn a metal worm. over time the worm wears the gear out. you have three options to fix it. one, replace the motor. two, take the motor out, take it apart rotate the gear inside the motor (only half the gear makes contact with the worm) so the other half of the gear is now used. it should be good for about another year after that. three, take out the motor break it apart and replace the nylon gear with a metal gear. if you take the motor apart, you need to epoxy it back together, the motor is not designed to be worked on. a new gear should cost about 50 dollars. a new motor should cost about 250. but it will have the same nylon gear in it. good luck.
