Have a 2006 Dodge Ram 3500 Cummins and the Low beams are not working. The high beams and fog lights work fine. I can not find any fuses for the low beams, it is a different fuse box then my '05 Does anyone have a wiring diagram for this year? Could it be the timer or the staulk? I have tested the bulbs and relays any info would be appreciated.

the 06 is the strangest wiring of any model. when you turn on the lights the switch sends a signal to the ecm and the ecm triggers solid state devices to send power to lights. the two wires that feed the low beam go back to the ecm this is done for day time running lights and the ecm series the lights the best way to trouble shoot is to get a test light , turn on the lights, pierce the insulation on each wire do this first with the test light ground on negative side of battery then re do with it connected to positive side do both left and right side this will eliminate socket problem and determine if ground or hot is missing now trace the wiring to the ecm if nothing looks bad there you either have lost signal from switch or the pcm is bad

if one of your low beam lights is out the other one wont work either check the bulbs and make sure both hi/lo wires look good on each bulb.

Have you checked for codes?

My headlights and turn signals have done strange things in the past...

Resetting codes with my Smarty has resolved these problems.
