67 Barracuda Dash Dial lights

You can reach up and remove the headlight switch without having to remove the instrument cluster or anything. Get out your service manual or wiring schematic for the dash and put your ohm meter on whatever two terminals are needed to light the dash. If you have no continuity then you most likely have bad switch. I just went through this with a 67 Valiant. Luckily I had a spare switch and now that dash lights work perfectly.

Just make sure you turn the knob back and forth to see if you can get continuity on your tester.
