Hello, my gauge lights aren't working on my dash. When driving the rpm, mph and gas gauge needles are working they are just not lighting up when head lights are turned on. When the key is in the on position the check engine light, e brake and door ajar lights come on. Also the lights for the ac controls do not come on neither. Checked all fuses and they are all good. I was just wondering if anyone had any clue of what might be the problem before I tear my dash off and start chasing wires one by one

Brake lights are functioning. All exterior lights including reverse and side markers are functioning. Interior dome and floor lights are also working.

Have you checked out the dimmer wheel for the interior lights? It has an 'off' position that is sometimes a problem.

I wish the link still had pictures that functioned so I could see how to replace the resisitor.

My 85 and 86 both had a bad dimmer transistor. Its located to the right of the steering column under the dash.

start by looking at schematic on page 274 of the Haynes manual,
look at brown (brn) & dark green With white wired( dkgrn/wht)
BASIC KNOWLEDGE OF ELECTRICAL SCHEMATICS MAKES YOUR LIFE EASIER
replace fuse 13,make sure male & female are bright
...............now the fun stuff
pull the light switch & clean the male blades,& female they insert into =EASY CHORE
clean dimmer switch connectors also
a test light is best for this work,,when you locate potential problem ,,use jumper wire to go around it... U
ANY BAD CONNECTION CAUSE INTERMITTEN CONNECTION WHEN YOU HIT BUMPS ,WHICH RUINS THE DIMMER SWITCH eventually
you can glue sand paper to piece of thin flat plastic from plastic juice /soda bottle.. just cut to size keep a few of these in the tool box,, really handy to clean connectors ,,better than metal file
of course check the ground connections in this area (black wires )
