Dash lights, interior lights do not work. Fuse is good, possible dimmer switch?

buy it used like this or just failed now 30 years later? called out of the blue failed?
name all lamps in the dash that fail there are many
we can not guess them all.
the dash has piles of cluster lamps. (errors) and has background lamps that are DIMMER controlled.
dashboards have many lamps even the shift lever does.

1. car starts and riuns good
2. HL work key on and off, headlamps
3. park ing lamps work
4. dome lamp work (door opens domes glow)
5. cluster error lamps work or not.
6. cluster back ground dimmers work or not.
7. AC panel dead. lamps yes.
8. the car has 2 or more fuse boxs, you do know that riight
9. all facts matter above to fast accurate diagnosis. (I give up)
10. this car had option AUTO lamps , got that?

F13 ,IP box is fuse that can blow. is park feed (HL) to dash
and via the DIMMER. and also glows Illumination on AC panel
THE AC active lamp is a whole other matter.
if the DIMMER works on high but not below that is a BAD dimmer control, for sure)

IP fuse F6 is for AutO Lamps OPTED CARS.


THIS MAKES NO SENSE
I the dimmer switch turn the interior light on still so I'm assuming it's still good
IF DIMMER FAILS FAILS ALL MODES THE FUSE IS BLOWN
IF DIMMER FAILS ONLY OFF HIGH THE DIMMER ITSELF IS BAD.
IT HAS ONLY 2 PINS ON IT.
HOT WITH PARK OR HL ON.
THIS PATH IS DASH AND CLUSTER ILLUMINATION FEED
OR BACKGROUND LAMPS, ONLY, FOR NIGHT DRIVING.

Those are different unrelated circuits. The dash lights are from the Head/park light switch. Make sure the dimmer rheostat is not turned way down-you know, how you turn the knob for brighter or dimmer interior. If the bulbs are good on the backside of the cluster, it may be the switch.
The brake light switch is on the brake pedal. If no power to the switch, check the stop light fuse. I believe it may be same fuse as the hazard lights.

That is an easy fix, it is one of two issues.
(1) Check the fuse for the dash lights. If the fuse is ok , it will be (2) burnt out bulbs. For #2 - you have to remove the bezel surrounding the dash cluster. Then look to see if the bulbs are good or have burnt out. The new bulbs are available at almost any auto parts store.

Check the dimmer switch! Head lights should still work if dimmer! But no interior dash lights! Fuse for lights is under hood in fuse center! If it is the headlights I would check the switch and if applicable the relay! I assume you have checked for ground at the light and power at the headlight fuses!! Good luck

either blowed fuse or check dash lights dimmer switch, make sure dimmer switch is not turn down completely low,that will cause your dash lights not to light up.

yes it can be a fuse, most cars have a dimmer for dash/interior lights if fuse is ok it may be the dimmer switch.

Check your fuses. The dash lights are on a different fuse. Also check dimmer switch. If its not one, then it is the other. Try working dimmer switch quickly back and forth( with the lights on when it's dark so you can see if they come on).

check dash light dimmer switch for power,if no power replace the headlight switch.if you have power at dimmer see if you have it coming out of the dimmer switch,if no power replace dimmer

make sure the dash lights dimmer switch is turn all the way off.it make your dash light not light up.if its okay check the wiring.

TRY THE DIMMER SWITCH MAKE SURE IT'S NOT TURNED ALL THE DOWN,IF THAT DOES NOT WORK FROM THERE YOU MAY HAVE TO REPLACE THE DIMMER SWITCH
