No dash lights 69 Roadrunner

This is driving me crazy. Trying to track this down, the way I read the diagram, the power runs from the light switch to the panel light switch (dimmer), back thru the fuse box before going to the instrument lights, am I reading that right? I have headlights and parking lights, but 0 volts at the fuse box. Is the panel light switch bad, or am I missing something?

Check the connection at the back of the switch and also the dimmer (dome) switch. I had the same problem. Cleaned the dome switch with electrical contact cleaner, dried it and behold, Instrument lights. Good luck.
PS - Check all your dash bulbs. They are a bitch to get to.

Thanks, thats the switch I was thinking the problem is with, so I will try the contact cleaner tomorrow and keep my fingers crossed! Ill report back!

Hopefully you don't have to replace that switch as I have seen the for no less than $ 135.00 and as high as $ 210.00 per switch. That ain't cheap!

sigh that doesnt suprise me, nothing else has been cheap on this one.
Ok, pull the plug from the back, have 12 volts coming in, 0 going out. sprayed the connection with contact cleaner, put it back and I have 0 to 6 volts coming out (on the lower half of the dimmer range), before dropping back to 0 on the upper half. Im going to pull the switch and try to clean it with contact cleaner before replacing.

I used a jumper wire on the plug to bypass the dimmer and got 12 volts to the fusebox, but still no dash lights, so I guess the next step is the plug on the back of the instrument panel. Any way to pull that plug without taking the instrument cluster out? I dont want to have to pull that lower pad off again if I can keep from it

My first post here. I had the same issue with my 68 Dart, and it was a pinched wire in the steering column going to the PRNDL selector. Once I wrapped up that wire with electrical tape, walla, it worked like a champ so check that you don't have a wire grounding out.
