SOURCE: electrical draw CTSY FUSE
I wonder if the buzzing is coming from the key switch ? (ignition ) . CTSY is always HOT ! you need a wire diagram to see where CTSY wires travel to & from to isolate this draw . I found that the CTSY 20amp fuse is also wired to the parking lights 20A fuse @ fuse block . start there, check all wires, grounds to parking lamps, and switch, it might be your headlight switch thats causing your problem ! replace it and see what happens !
