Hi fellow oofers! I have not contributed on this forum for quite some time. However, since the temps up here have taken a dramatic downward spiral ie: -6c last night and double figures forecast over this weekend!
This morning I had to scrape windows and started the old girl up, and switched on both demist and heated rear windscreen. There was a slight noise when I turned on the HRW and it slightly made a difference to the engine revs but would not stay on.
However, this evening when the temps had gone up slightly the problem did not appear!
Any idea chaps?

Cheers

I guess it's possible that the climate panel disables the rear screen if the battery volts drop too low. Maybe that was it and the battery has now recovered?

Thanks Kevin! The battery is only 3 months old, a Bosch, so good quality. Is there a relay in the boot area as the noise seemed to come from that area? Of course with the temps up to 12c the demister switches on without any problems.
