When I turn on the lights all the dash lighst and everything bottom/control going on red, that is normal, but the bottom that control the AC air direction stay dark, its the only bottom that not turn on, but just the center, around the bottom the red light is on. I have the all the AC controls electric. Could be a electric sensor?

 

If you have the Auto AC (which it sounds like you do), there are 5 bulbs behind the unit. You will have to remove the complete radio assembly & change the bulb that is burnt out.

Thanks, I guess that will be the problem and you right, I have the Auto AC. Ill hope remove the complete radio assembly won't be difficult.
