2001 Dodge Ram 2500 Cummins. Left headlight will not shutoff when truck is shut down... Right turn signal stays on, and 4wd light stays on when truck is running? Any help is greatly appreciated.
Thanks

 

Sounds like a ground problem. You might also want to remove the panels off of the steering wheel column and check the wires there if you have a tilt wheel(common prob). Other than that, get a Haynes and download the free FSM from the FAQ /DIY section and start tracing wires.

 

Either a ground a or a stuck relay.

 

Are the headlight switches on the 2001 as problematic as earlier years? May want to pull it out and peek at the back side of it...
