I know this topic has been in this forum before but I just wanted to clarify a couple things. All my lights on my 69 charger are working except my dash lights and the park/running lights. They were working last year but I think I dicked around with the dimmer wheel too much. I’ve checked the fuse and the grounds look good. So, to replace this switch, can I just unplug the 3 wires from the back and unscrew it or do I have to take the cluster face plate off from the front?
 
pull wires and screws and your good.
 
The dimmer wheel will have nothing to do with the park lights. Recheck those fuses. The park light fuse 20 amp has to be good as that also feeds the dimmer. Out of the dimmer you have a 3 amp fuse that does the instrument lighting.

Well as I understand it, voltage has to pass through the dimmer switch and then to the dome light and tail lights in a series circuit fashion. My dome light works when the doors are open. The signals, brakes and flashers all work. I checked the fuse and it’s good. That switch has to be broken, does it not?

No..........The dimmer switch grounds the dome light. The dome light is always hot on the pink wire. Yellow is the ground side. The signals, brakes and flashers have noting at all to do with this circuit. How did you check the fuses? And again that switch does not have to be broken. You are not understanding it correctly.
 
Parking lights and dash lights are definitely related. They share same input source into the light switch, then the light switch spreads out in diff outputs.

I'm not saying the fail is related, since you can get two diff failures, BUT definitelly if the input signal or the switch internally gets a failure related to this line, you can get this failure affecting both output circuits
 
Fine69 you can disagree all you want. Get the manual and look at the wiring diagram.
 
Is true. Dome light function is an on/off ground trigger built into the dimmer wheel assembly, not a voltage running throught the dimmer wheel rheostat. This ground trigger is activated by a points lever pushed by the rheostat ceramic piece and conects to the dimmer wheel chassis ground.

We are talking about two diff functions with diff signals handled by the dimmer wheel assembly.

The 3 wires to the dimmer wheel are, input coming from light switch ( from parking circuit ), output to dash lights ( getting a 3 amps fuse first into the fuse box ) and ground to turn on dome light.

Well don’t be offended. I just don’t agree. However, I’ll still go through it again and let you know what I find.

Just wondering if you found the culprit?

EVEN THOUGH, I checked the fuse 3 friggin times, it turned out to be the fuse. It didn’t appear burned and maybe it was a dud but swapped her out and let there be light.
The switch still isn’t turning on the dome light though. I’ll have to look into that.

I can agree with this answer.

To be honest I forgot about it. However when I saw it pop up I had to make a sound. You were like a horse with blinders on and when that happens you go right past the in your face fix. Sad thing is I sometimes resemble that remark. Fuses--------Never trust your eye. Test light or voltmeter.

PS. I could have just lied and said it was the switch but I chose to face the music.
