    Some possibilities, corrosion in your dimmer switch, broken wire, bad ground, or loose connector where the plow harness taps into the truck wiring, bad relay or connections to it. There were a few threads on this topic recently. Search for those and you'll see some of the results that were found to be the cause, which may help you isolate your problem.

    hi-low headlamp switch broken

    hi.your headlamp switch is most likely faulty.its located on top edge of steering column aprox 8 inch rearward of firewall.tools needed are phillips screw driver,15 mm socket wrench,1/4 5/16 3/8 sockets and if the truck has air conditioning the air ducts need to be moved slightly downward.Good luck. welded wrenches in BURRR pa.

    Floor Switch

    Seems like the high beam switch on the floor is bad. Salt from your wet boots will eat it to nothing causing it to ground itself out.They can be bought at any automotive store for under $6. Pull the carpet back and you'll know right away if it's hit.

    Hi Brent.
    My dimmer switch in on the colom. I thought it might be gone as well. but it will dim the plow lights to low and high beam. so im going to get a head light switch see if that works.
