When I turn on the headlights, my dashboard and radio background/ambient light go completely dark. I'm not sure if this is a wiring issue or a bulb issue? The radio backlight is on when the headlights are off. Once I turn on the headlights, the radio background light and the entire dasboard console goes dark.

Help and guidance?

Thanks,
Paul.

 

Quick question???? Is the rotary dimmer *** turned down

 

check all of your fuses
