Q: My dash lights don't come on but all other lights knobs etc do

asked by on

My dash backlighting does not come on. All the other lights do. My controls all light up, my dome lights work, the dimmer adjusts the lights that do work. Every once in a blue moon, my dash lights will come on for a day or so and then nothing. Is this a software issue with my chassis computer?
