Re: 99 Sunfire Dash Light & Radio Lights turn off when you turn on head lights
So then would it be more accurate to say the dash lights don't ever come on? They shouldn't be on when the headlights are off. Check fuses and bulbs there.
The radio is designed to dim when the headlights are turned on. There is a wire that goes from the parking light power to the radio to tell it when to dim. The dimming function is internal to the radio, so most likely the radio is bad. Cutting the dimming wire would keep it on full brightness all the time, if you don't mind the increased brightness
