2001 f 350 light problems Ok changed the multi function switch ,tested the light switch changed relays and fuses same problem. Disconnected every ad on . High beam light on dash always on, put on low beam looks like high beam ,put on hi beam looks like very lo beam , fog lights will work all the time (shouldn't with high beam ) my lighting problem might be just a coincides with hooking up a plow . Oh by the way when the plow is hooked up it is the same, lights go out on the truck but same high low problem on the plow.
