Hi, Sorry was away a few days (almost 1,000 miles added to the GV and no issues with cutting out I'm pleased to say). Yes, I found the same thing, the heater was disconnected, when tested/reconnected it was a dead short, looks like it's in the wiring loom somewhere up behind the glovebox as it passes between outer and inner bodywork, I've not yet traced it as I simply cut it back under the carpet and wired it up elsewhere, happy to give details if you need it. In terms of my cutting out, no I don't think it was ultimately the issue, though may have been one of many combined together causing me issues. Unless you have problems I'd not worry about it as also cannot see it making a huge difference.
