Hi,
Last weekend the rear window demister stopped working - no idea why. The icon still appears when the button's pressed, but that's it. The boot's full due to audio equipment so I'm not sure if that could've damaged the wiring. All of the fuses under the bonnet are fine - could it be a fuse by the drivers footwell? I do have a spare windscreen but I'd really hope I don't need to go that route.
Regards,
Carl
