I have a 1993 chevy 1500 and my dash lights, running lights and horn stopped working. Why??
My head lights, blinkers and brake lights work.
Iv replaced all fuses
Replaced light bulbs
Replacd head light switch

What's next??

Iv checked all grounds.
I know the dash and parking lights are together. Today I'll be replacing
The dimmer switch. But if this doesn't work what's next?
Help!

 

Your are not having problems with any of the fuses blowing?

 

im having the same problem as bigk but everytime i put in a new fuse it blows immediatly.my gauges work but they dont light up and my horn stopped working at the same exact time

 

Check the horn itself, it may be shorted. Also check the horn relay.

 

Also check the headlight wire harnesses, they may be mis-wired. Last time I got the same problem with a set of aftermarket headlights I got from Xtralights blowing my fuses continuously and found out that the lights are wired incorrectly. You may want to ask some online store like Xtralights for technical support.
