Soooooo!! none of my dash lights are working. 1967 Coronet, where is a good place to start looking? It's probably some kind of grounging issue. It sat outside for a long time, not running. I think that is what is going on with my tag light, too!

2 gauges and the radio not working, either.

Did you try twisting the headlight knob to see if the rheostat is working? It adjusts the dash lights brightness?

It does twist but doesn't seem to dim any of the other things the does work, it does turn on the dome light. Only other dash lighting that works is the high beam light, and turn signals lighting.

Think the hazzard is a little funky, too!

The headlight switch would affect the lighting issues, but since some of the gauges are also not working, I doubt that the switch is the problem. The instrument cluster is grounded by the metal screws that attach the cluster to the instrument panel frame, so that shouldn't be the problem either. I would venture to say that you might have a problem with the voltage regulator that plugs into the back side of the instrument cluster and regulates power to the cluster lighting, or you might have an issue with the cluster's printed circuit board, possibly either a break in the circuits, or with corrosion since the car has been sitting outside for so long. Hopefully one of our DCR electrical experts will chime in and give you some options to look at.

The orange wire behind the cluster is the lighting wire from the headlight switch. Orange can be found running all lighting dash fixtures.

Thanks guys! I just need to find some time to get the dash pannel pulled. I guess the flashers are back behind there somewhere, too?

No those are tucked at the bottom of the dash frame under the left side of the glove box.

Update, pulled the dash cluster out to clean and paint. found a post pulled off the printed circuit, it went to the purple wire. assuming it was to the temp gauge, it now works. figured that would take care of the new dash lights not working issue, it did not. earlier I replaced the headlight switch, and that got most working, but not all. Changed a few bulbs and had almost all working, then they just stopped. What do ya think now? regulator, printed circuit, bad wire, how could I test out of the car, power up the orange wire?

P.S. I soldered the post back on the printed circuit.

Everything works except the dash lights! and the radio light. All bulbs good, as well.
