ill try to explain this the best i can, lol
the other day i was driving at night and all the dash lights went out... at the same time! except the turn signal lights... so i fiqured a fuse checked all the stab lock fuses under the steering colum, no dice, then i fiqured the lightswitch no dice.. so i fiqure did all the lights burn out at the same time? impossible i know but i checked haha and no they are all fine. is there some fuse some where in the car that handles these lights that isnt in the fuse block? the guages all work but no lights! and it sure makes it hard to see how fast your going at night

 

anyone??

 

mine does same thing from time 2 time its in the headlight **** maybe a loose wire try turning it left or right a little its got 2 do with the gauge dimmer

 

more likely the Primary light switch or the pigtail going to it.. make sure you look for burned connections.

 

I agree if all your fuse are good,and all your gauges work which shows power is getting to the cluster,then you have a problem with the headlight switch.The rheostat that controls the dash ligh brightness,and turns on the interior lights,don't wear well with age.
