Since I have the radio panel and speedo out of the truck, it gives me a little easier access to everything else under there.
The high beam indicator light is the only dash light that functions. None of the other gauge lights come on when the headlights are turned on.
I verified that all the bulbs work by putting them in the high beam socket.
I haven't begun to troubleshoot this at all but figured I'd ask what the most likely place is to look first.
I rewired the headlights a few years ago from the dimmer switch to the headlights themselves and all that works perfectly. Wiring under the dash is in generally good condition. Since all of the lights do not work, it seems logical that the problem lies at some point that they all share.
Headlight switch? Is there a junction somewhere that ties them all together?
