My friend has a problem with his headlights. His low beams don't work but his fog lights are on. He is able to turn his high beams on but they won't stay on.

Does anyone know what the problem may be?

Thanks.

 

Not sure, but I'm thinkin relay or the switch.

 

I had the same issue. It was the switch in my case but you should check the relay to.

 

Multi function switch. It controls your wipers and turn signals as well as your lights. I had the same problem i would go to flash my brights at night and it was hit or miss if the low beams would come back on or not. 60$ later problem was fixed. It is a fairly comon problem with these trucks.
