My interior lights for my hot/cold and fan are out below my stereo of my 06 Scion XB. I'm trying to diagnose what would be causing the lights to go out. Would having one burned out bulb cause all of them to not work? I checked my fuses and they all appear to be good. Any ideas? On a side note, the light for my automatic shifter went out but I checked it and it was burnt out. Replaced the bulb and now it's all good.
