Re:wiring diagram for 2006 peterbilt 379 mike 6-12-08  
I desperately need the dash and fusebox wiring diagrams/schematicsfor a 2006 peterbilt 379. I can't get the headlights to shut off. Had long time unknown water leakage and corrosion in fusebox. Used electrical spray cleaner and replaced fuses. Headlights won't shut off! this isn't a toggle switch type dash. HELP!!!!

Clutch fan won't cycle. Have checked fuses none blown, but fan solenoid doesn't have fire on it. The manual fan switch has fire on one leg of it but won't cut fan off it stays running all the time. Where does it get its fire from, I don't have a wiring scematic to even know where to go from here. If at all possible please help, Peterbuilt won't even tell me where to start, they just want to make a fortune off a strugling driver like me. With the economy like it is I can't afford to let the fan clutch burn up its already making a hell of a racket. HELP PLEASE

Hi NO DASH LIGHTS THX
2001 Pet 378 engine fan runs constantly Gerry 7-26-12  
The engine fan in my 2001 Pete 378 stays engaged all the time. I feel it's wasting fuel and hp. The engine is a Cummins N-14 Redtop. Could this problem be connected to the A/C compressor being locked up? I've disconnected the compressor, it keeps blowing fuses. Anyone got any ideas?

Tried changing stock headlights. Now when I turn them on they come on then go off then come back on and off. I have already replaced the relays. Did not fix the problem.
