I'm borrowing a 2008 Spectra from a friend. When I turn the car on, the lights on the clock, radio, climate controls and odometer work fine. As soon as I turn the headlights on, none of those lights work. I don't have any interior lights, other than the tire pressure light. The headlights, tail lights, and turn signals work, and moving the knob to adjust the brightness of the speedometer doesn't do anything either. Since the lights work when the headlights aren't on, I didn't expect it to be a fuse or bulb issue, but I checked those just to be sure. (The fuses in the car, and the ones under the hood.) Does anyone have any ideas what it could be?
