The fault is probably a faulty driver's side air temperature flap motor"
Any thoughts on that chaps?

Can only advise that in my case after the AQS was replaced in mine, the hot air was restored, even tried unplugging it and cleaning the terminals and dusting the sensor before replacement to no avail.
I'd try and get the codes read, as I was advised by my dealer that the AQS being faulty can bring the bus down that controls the heater flaps etc.
OH!, and the passenger heat would not heat, after replacing the unit, again normal function restored.
