Can anyone tell me how to fix my dashlights? It has a new headlight switch. and ive tried swapping out the entire cluster and circuit board. My cluser dont light up and my ac or nothing else lights up either. The cigarette lighter/radio and all that works fine. I just dont know why the lights arent working

 

What year is your truck? You can download a service manual for it from here.

 

Did you try turning the ****(rheostat) to the right?
