The motor on my N/S headlight beam adjustment is on constantly when the headlights are on dipped beam, the noise goes off when I just have the side light's on, are these motors independently fused? if so does any one know what amp fuse and location or can I just pull some wires of the motor or switch for a quick fix until I have time to replace the motor, as it seems to be taking too much charge out of the car battery.
