hi all
need some help here......just bought a 1994 silverado ........came from Virginia.......I live in ny
truck has never seen a ny winter.....so you know how exciting it is to have an older truck that
has never seen a ny winter.........

well my problem is with the dash lights....I have none.........pulled out the panel to check the switches.....and ekes its a mess.....some one did some cobbled up work on it.....but anyway
the dimmer switch for the dash has 4 wires......one is end is hot with head lights on.....other
is when turning on the dome.....2 center are not hot at all........for the heck of it I hooked test light to
live wire and checked both center wires again....light does come on....but does not dim when
turning switch.....don't know if this is norm.....

this is a very nice truck and would like to get lights working.......any help would be appreciated
maybe a wire diagram would help

thanks a gain Keith

sounds to me like the same thing that might have happened to me.

I would use a Digital multimeter and check continuity on teh switch as mine just burned out from too much current going through it.

I would start there... go to a boneyard and grab one quick and easy ;)
