69Shortstep, I was rereading the thread and just thought about something. I don't have my truck here so can't check my theory.

You say that the only thing not working are the lights that light up the dash panel and heater control. Correct me if I'm wrong, but all of these small light bulbs are controlled by the light switch rheostat. I don't believe that the rest of the lights are affected by the light switch rheostat. So maybe it's the light switch itself that's the culprit. If the rheostat is bad, it will not allow the voltage to go through... Something else to check.
