Re: Heater not working and fan blowing at my feet!
OK, forget the direction thing, I've fixed that following reading another thread (the flap under the top vent was stuck, so greased it temporarily, will cut back in daylight sometime.
Still have the problem with the heater though.... One clue is that on the "max defrost" setting, it usually uses moderate fan speed when the engine isn't up to temperature yet and goes to maximum fan speed when the heat's there.... but when I tried that it stayed on the moderate fan speed despite a hot engine.
What controls whether it allows warm air in? Radiator temperature? Coolant is up to 'max', so there's certainly enough water the rad to feed the heater. Inside temperature sensor perhaps?
Any thoughts greatly appreciated!
