ok i have a 93 silverado and i got off of football the other day and it was dark out so i turnd my lights on and the dash wouldnt light up


and i have checked all the fuses

 

try tapping the headlight switch first, the dimmer may have a bad spot and needs a little persuasion, also do the dome lights turn on when you try with the switch, next i would find the power going to the switch and jump it around with a paper clip to make sure the wiring is good, just make sure you dont hit a ground then you will have to replace fuses

 

ok ill try that
