Hi all! Today when I started up my car to go to work, I've noticed my instrument cluster was blank. Temperature gauge, speedometer, trip computer, nothing worked. Other electrics were not working either, windows, even the turn signals. However, the headlights turned on just fine and the brakes seem to be fine as well, so I was able to drive to work. As I've said, the car runs and drives, but electrics aren't working at all (except for the comand system, which works, barely). Is this a sign of a dying battery? Or is it something worse?
