Default No low beam headlights 2008 Kodiak 4500

No low beams. Replaced both low beam bulbs. Have all bulbs lit on high beam selection. Have daytime running lights. But when you select low beams only just have the marker/tail lights and no head lamps. I also checked all fuses. aAnd the DRL relay is OK. I'm thinking the high low selector switch is bad? And not the main headlamp switch? Any Techs please chime in. Thanks

The low beam lights work through a relay that is located in a panel in the pass side dash below the air bag. There are two captured #10 bolts in the bottom edge of the panel. There is a fuse and relay location ilistration inside of the panel.

Thanks Denny, I checked those fuses. I think the relay is the DRL. Any other relays or idea's. Thanks

Do you have DLRs? Chances are you don't. If you don't change the DLR relay if your fuses are good and you should get both lows and DLRs. Let us know.

Further make sure that your parking brake is fully off for the DLRs to come on.

I seem to remember reading several posts about a wiring harness on the fender well chaffing on some kodiak models and weird lighting issues.

Might be worth a poke around the engine bay to look.....

Thanks I'll check the harness out. I do have DLR's and I did make sure the Ebrake is off. I just don't have the low beams. It's wierd. I think maybe it's the high low switch in turn signal lever. I guess I have to pull the wheel and r&r it. Thanks

Question

I've looked at the wiring diagram and what I see is that if you have DLRs you are getting power to the low beams. The low beams get there power through the DLR relay. It almost has to be a bad relay.

Ok, I had swapped out the reverse relay with the DRL relay. They both use the same relay. I wonder if they could both be bad?

Not likely. Back in the diagrams I go.
