I have a 2007 1500 and the pass is out on the truck and my plow. The high beam works on both sides and the bulbs are brand new. I checked for a fuse but there is not one for the head lights, if any one has an idea shoot it my way.

 

There's gotta be a fuse, relay or breaker somewhere. I'll be dogged if I can find it in the diagram for my '03, though. Weird.

 

Did you chase the wires for the light and look for a short? While I was crawling around under my truck the wiring looked as if it was spliced and fixed with electrical tape. I think the wiring on the Ram sucks ***. (Assembled in Mexico.)

 

It just don't make any sence that the only the low beam is out on both the truck and the plow. i chaced all the wires and every thing looks good, and couldn't find a fuse or a relay anywhere. next step is to test the wires and see if maybe the plug itself is bad. I let ya know and thanks for the input.

 

spray wd-40 on he recepticle that hooks up3 the headlight if u do this and it workd u know the plug is bad if not, fuse. if u cant see a fuse think about volt wire a lot of wires now rey on amps to melt causing replacement of a wire . just a thought
