Dash lights have me flummoxed

[PatinaBeforePolish]

Instrument cluster and HVAC lights started working only when headlight switch rheostat was in a certain position, now nothing. Ashtray and cigarette lights also not working. Replaced headlight switch and hazard switch with known working units, still nothing. Trunk light and door buzzer share the same circuit and they work. The feeds all use the same wire color coding; white or light grey with a blue stripe. Any suggestions on what else to check?

Pull the headlight switch and stick a meter on the wire for those lights, should be easy to ID by color code, and see what you get, voltage wise. While not a fix, it will point you in a direction of being the switch or past the switch which would actually be a fairly short run.

Thanks Mike. It was the headlight switch but I didn't figure it out until I happened to notice a taillight, and side marker lights were out. Turns out the lid on the fusebox incorrectly identifies which functions are on specific circuits. I must have shorted something in my fiddling and was staring at the wrong fuse all along. I hope I have to never remove and re-install the driver's side lower panel again!
