Gauge Lights Do Not Work

[bordin34]

I turned on my lights yesterday and the gauge lights turned on and everything was fine. The all of a sudden the gauge lights went out and it was dark inside the cabin. Are they controlled by a fuse? 1974 Charger SE Rallye Dash

I believe there's a 2 amp fuse in the fusebox for the dash illumination lights.  Did you try playing with the part of the headlight switch that controls the brightness of the dash lights to see if you can get them to at least flicker?   It may be the rheostat in the switch.

lighting net uses two fuses two power inputs

One input directly from Battery what feeds JUST the beams. Comes from a splice on underdash harness.

Other input what feeds the rest of system that feeds everything, from parking up cluster( except beams, dome, map, reverse, turns, hazzards and brakes ) lights.

This source comes from 20 amp fuse. Is a shared function fuse with cigar lighter, and is number 4 ( the bottom one on the batt side of fuse box )

Then the second fuse is an output protection just to cluster ilumination. Is the number 5 fuse box and is the top one at the accesories side of fuse box. This fuse is not linked to the buss bars on back of fuse box, so is not really part of "accesories" side.

Thanks I'll just replace every fuse and see if I can get various other things to work.

try playing with the dimmer switch sometimes you need to put some pressure on it and wiggle up and down and it works

yes is true, it could be also that the problem, rusted or sulfated resistance spring... even not putting pressure, that is on 2nd gens ... 3rd gens are spining the lights switch knob itself
