I have a 2006 3500 and the pass. side headlight no longer works marker and signal are fine. Changed out bulb from other side to check. Bulds are fine. Any ideas what it could be or what i should be looking for.

Thanks for the help.

check your fuses. if its just the running light that doesn't work then it might be the fuze to the right side see if your tail light is on too there is a fuze for both sides for the running lights.

 

"Fuse" Sounds like a possible fuse box issue.

 

i have the same general issue with my dakota the wires rub on the sharp edge of the inter fender well i would look and see if the wire lumb is rubbed threw. all check fuses and grounds. most of the time there is a right and left side fuse. becaue there seperated now so that one light doesnt dim like that onlt Tj jeeps and F100 fords use to.

 

Depending on if you have a after market headlight that has a higher draw then the stock light, i would check the ecm panel underneath the fuse block in the engine compartment. I personally put after market head light assemblies in, and ended up burning out the ecm board as a whole. If you test for power at the light itself, it will appear to be fine, until a draw is put on it, thats when it shorts. Have to test at the actual circuit board.
