if you have current to the motor, but the headlight mechanism is not operating it may very well be the gear in the housing. the stock gear is made of plastic and they break all the time and jam up. they are the same gear that works the window mechanism. if the gear is not the problem now it probably would be in the future. all of the vendors sell replacement gears made out of brass (or bronze, maybe)including the sponsor of this website. I would replace it while you have the assembly apart.
