Seat heating died, then the central console and the radio...any hidden fuses?

First the heating went for the seats, then the climate controls and the radio died. I'can't find any blown fuses in the dashboard fuse box, and my manual is in German. Surely a fuse or two have blown, but where are they?
 
Believe it or not, but it seems like the climate controls, the seat heating, the window washer pump AND the radio are all on the same 15A fuse.

I haven't been able to pinpoint where the problem is, but at the moment I'm suspecting a short in the driver's seat heating element.
