I'm still having problems with my cabin heater despite several attempts at sorting it out
The heater blows hot or cold - there is no mix control.
The heater only blows up through the centre vent - nothing to the windscreen defrost.
So far it has had the control unit replaced at Autolusso and I have replaced the actuator that controls the lower flaps (a difficult thing to access!) I'm told that there are 2 flap control actuators, one on top of the other - is this correct?
Before I start tearing out the dash to get to actuators, is there something else this could be? Are there any hidden fuses or relays or known dodgy earths or anything????
Fixed it! Turned out to be the control unit - one with the 3 knobs on it. Had a hunch it could be the controls as I'd tried everything else - lol. £10 off eBay. Now to find the leak in the aircon system ....
