I have a 1993 chev ext cab 4x4 with the 5.7L The running lights and dash lights dont work. I have checked the fuses and all seems fine. is there something that i should be looking at like a relay or anything common that has happened to a truck like mine.

 

grounds and the switch
i dont know how they are on those models, but the c/k series has the grounds right at the headlight assmblys
