I have just purchased a 2004 3500 DRW 2wd. The right side headlight was out thought it was bulb. Replaced the bulb, NOOP!
The headlight will work on bright but no low beam. Also the light out indicator in the instrument cluster is on.
I have checked voltage on this plug, low beam I am only getting 7.34VDC & bright 12.35VDC.
When I check the left side the voltages are 12.35VDC on low & high.
It appears that I am not getting enough voltage, but I cannot locate the relay for this truck.
Can sameone here shead a little light on this for me or if you have share the schematics for this truck so I can trace this out.
Thanks
