    It could be a bad bulb, bad headlight harness on the plow side, or bad headlight harness on the truck side. If its not a bad bulb I'd test the low beam wire on that side of the plow and go from there. I just had a problem with the wiring harness on the truck side being bad at the plug causing the lights to intermittently turn on and off, and also causing the left high beam to not work. Replaced the harness and works fine.

    I think that you need the configuration plug changed

    What do you mean by configuration plug changed ? All bulbs are good, how do I find the wiring scamatic for it?
