 Does anyone know where the rear window heater/demister fuse is?

It's stopped working and I've had a quick look around and cant see it in manuals or on on the fuse lids.

 Hi, have a look at following site, - Click Here - which has various versions of fuse / relay info listed. Not sure which model or fuse box type you have, but I can see at least 2 references to HRW. I cannot vouch for quality of info, but if you've not seen b4 maybe worth exploring? - John

 Thanks, but oddly the type 2 internal fuse box has a heated window fuse and alsoBFH3 - whatever that means.

Will need to have alook and see what fuse board I have

 Hi, I have no real experience of this but maybe you will have both boxes, as it states BFH3 is located just below the main box? BFH3 contains both (F)uses & (R)elays. F1 in BFH3, which is designated as HRW, looks a bit odd in the schematic which implies it is more than just a fuse? Thinking logically it might be some sort of TIMER IC, which switches the HRW off automatically after a set time to reduce unnecessary power drain.
If this logic is true and F17 is OK in the type2 box, then it may be F1 in the BFH3 is the problem, as both would need to OK for the HRW to receive power? Just a suggestion to consider, John

 Problem found, a bit more basic:



And a bit of careful soldering has it all working again.
