The verticle headlight adjustment screw backs all the way out without raising or lowering the headlight. It will come completely out and it seems it somehow has come loose to whatever adjusts the verticle beam of the headlight. Can't figure how to get it back to adjusting and the headlight is now aimed directly into the ground about 6 ft in front of the car and I can't seem to get it to "reconnect" to whatever the adjustment piece that it was originally hooked to .... any help here????
