I don't have illumination lighting for my heater control unit on the dash. Is there supposed to be illumination here with the headlights on? Seems there should be. I have a 1990 4runner. All other illumination lighting is working correctly.
Thanks! glad to hear it is any easy fix. I've had the vehicle less than a week. Thus, my first couple of times to this board. Do you remember how to get to the bulb?
