Hey everyone,
I've got an 07 Gcoupe 5AT. A couple days ago, while driving at night my car suddenly experienced several electrical problems at once. As of now, the car:
Won't go into night mode (taillights won't turn on, dash lights don't change even when headlights are in the on position)
Popup nav does not pop up
Aircon controls start as off when I turn the car on (car doesn't remember the last setting, resets to off)
Headlights DO work
Radio does work
Indicators DO work, but do not show up on the dash.

I checked the fuses and couldn't find any that were shorted.
Please help!

 

The first thing I would do is check your tail and brake lights to make sure they are functioning - if they are not obviously do NOT drive the car until you have the problem fixed.

If you checked the fuses and you couldn't find any that were "shorted" then you need to replace all your fuses, as they should all, in fact, be shorted. Blown fuses are "open". How did you check the fuses? If you didn't use an ohm meter recheck all fuses with an ohm meter and replace any open fuses. Make sure you check the fuses in the cabin AND under the hood.

Do you have any electrical modifications (aftermarket alarm, radio, radar detector, etc?)
