Hey any ideas or knowledge on why my headlight low beams just shut off on me going down the road? Ive checked the fuses and relays, changed all the plugs, and even put new bulbs in. Its just the low beams.....parking lights stay on and high beams r working.....i also noticed that my passenger side fog light has no power coming thru the wires to the plug

Are you running regular bulbs, or LEDs?

Could be a number of things. But Google search says the Headlight module is a common culprit. It's basically a relay with I believe electronics in it. Basically there's probably a bad solder joint inside it. Had something similar on a Jeep. Skip halfway ahead in the link below:


When you changed bulbs, did you notice anything 'funnny' with the wiring or connectors? Burned or otherwise? It's possible it could be other things incl the switch or multi-function switch ...but look into the headlight module.

Good luck. Hope it helps. Come back and let us know what fixed the problem so we're all a little smarter.
