Hi, I bought a 1989 Jaguar Soverign XJ40 about 3 months ago and the heater has been misbehaving since I got it. The fan works ok at all settings but only produces any heat when I have it on the highest fan setting (def) regardless of any of the heat seattings. I wonder if there is an additional (electrical pehaps) element in the demister setting? Does the heater ECU die very often? Any help would be most appreciated.
