I have no headlights no break lights and no left turn signals on my 2004 Ram 3500. One mechanic says its my PCM and my Distribution Box. Another says its some other sensor. Anyone have the same problem? Its a 5.9 turbo deisel

 

have you hooked up trailer recently?

also check all fuses ,both in the cab, and the engine compartment.

 

mine is older 93 d350 but it did that last year and it was the headlight switch
