Ok next wee job.my heating only seems to blow out warm air if its sitting at the lowest fan speed..try and turn up speed and the air goes lukewarm..tried bleeding the system and didn't help? Rear passenger blowers lukewarm as well...

Forgot to mention..i got an engine fault last week saying electric thermostat fault last occurrence plausibility...could it be related

Electric thermostat fault will not affect the heating.. I would take off the plug on top of the thermostat housing, under the pipe that goes to the plenum at the front of the engine, the thermostats can leak coolant into the plug and corrode and then seep up the wire and into the engine ECU and wreck it (I know it sounds far fetched but it does happen) If it is leaking then it's a new thermostat job...

Heating is probably a faulty motor for the blend flap, an IID tool and some other diagnostic tools will read the fault and also interrogate the system to check what does and doesn't work...  Pete
