EDIT: forgot to mention this is NOT my car!!!!
Well then don't worry about it.
Don't know about the Autos, but do the lights come on during the day?
The problem with my car is that whenever I turn the lights on, the radio backlight goes off. Whenever the lights are off, the backlight works, but once the lights go off, boom.
I believe my problem is that something on the AC control board is broken, and won't send backlight power to the radio when the lights are on.
Did you mess with the AC board at all?
