    I have a 2010 Freightliner Columbia. When I turn my headlights on my dash lights do not work and the 4 marker lights on my trailer do no work but everything else does. When I turn my parking lights on (to the down position) everything that is supposed to work does. I tried replacing the switch last night and it does the same thing. Any help please?

    I would look for a burned out bulb or fuse. I had a 99 Jeep GC and when the brake light burned out none of the dash lights would work.
