Help please! I've just been out to pick up a relative and drop them at home. The heater didn't warm up at all, not one degree! Yesterday it worked fine (and has done so from day one) and I didn't alter any settings this evening - it's winter and full warm is the standard setting. The vehicle was nicely up to temperature - temp gauge half way up the scale where it always sits once it's warmed up - but I couldn't get any hot air out of the vents. Both temp. regulators are at full hot and I tried cycling them both with zero result. Does anyone have any idea why it should just suddenly stop pushing out warm air, and if so, where should I look to remedy the problem?
Thanks folks, Steve Discovery II TD5
