Inoperative Headlights

[Hyatt Roadie]

I recently acquired a 2013 Newmar Mountain Aire model 4344 on a Freightliner Custom Chassis and have since discovered that the headlights are not working. All other exterior lights are working when the switch is turned on, but headlights do not turn on when the push switch is activated. The fuse panel does not have a headlight fuse that I can find. I spoke by phone with a Freightliner facility and they had trouble finding any information on the headlights even with the VIN. The unit is currently at a shop having some unrelated work done, but I intend to bring it to the Freightliner shop to have the headlights checked out in the next few weeks. Just wondering if anyone has any thoughts as what the problem may be or what I should look for since I do not see a headlights fuse on the panel in the exterior compartment. Thanks to all.

Headlights for almost anything should have a switch, a fuse, and a relay.
Fuse and relay are usually close together in a box, along with lots of other stuff under the hood, OR under the dashboard close to the steering shaft.
Just takes some looking.

Thanks Mike. I agree with you, will continue looking.

There are fuses for the headlights in a PDM. Have you checked the bulbs? It is possible for both to be just blown. Common issue is the lighting module failed. It’s a blue flat looking box with two connectors on it which should be in the first front compartment on the drivers side. Sometimes the connectors are melted and difficult to remove.

Thanks so very much. The unit is in the shop at present for some unrelated work, but I will check out the headlights issue per your suggestion when I get it back. Thanks again, much appreciated.
