Front lights dont turn on. on a 2000 ford f250 super duty disel
I would look for a problem with the headlamp switch. Also it could be in the multipurpose switch which is part of the turn signal switch I have seen both problems. You will need a test light that will light when you probe 12 volt wire. Follow the 12 volts from the fuse box, some trucks fuse the headlamps, so make sure they are all aright. Follow it to the head lamp switch to make sure it has current and if it does, probe the wires that are connected to the multipurpose switch. Make sure that the headlamps have a good ground and that they are both not bad.
