when operating my headlights, the drivers side motor will keep running for 5 seconds or so. Its been doing this for a while but the motion of the headlights has always been smooth and never given me a problem. Now when i retract the headlights the motor keeps running for that 5 seconds but now you hear a clicking noise and you can see the motor arm jump when the hood is up. The motion of the headlights is still very smooth when then go up or down, with no lazy eye or jumping. What is wearing out, or has already worn out? the gears, the bushings, will i eventually get a lazy eye or non working headlight. Sometimes i get a slight hesitation in the passenger headlight when its retracting, its hard to notice but if you watch it a few times you can see it. the passenger side was rebuilt right before i bought the car, and im not sure about the drivers side being fixed or not.
