I am having an intermittent heater problem with my 1.6 16v Astra Sport which I feel may be related to an electric/electronics fault.
The heater will sometimes start blowing cold air when the engine is hot, then it will blow hot air. I also have occaisional problems when I start the car, it starts no problem but then the engine management icon will come up and the engine will just idle and not respond to the throttle. If I switch it off and try again it usually works fine. I can't help feeling that this is part of the problem that is affecting the heater. Possibly a wrong signal being sent to a heater control valve??
I did have a similar problem with a Ford Puma, which did all kind of random things and the fault was traced to a faulty alternator.
