have you tried the re set? Hold off and auto for 5 secs. or until you hear the motors buzzing.

Do the pipes to the heater matrix run cold when the climate is set to maximum cooling  (pipes up inside the driver's footwell on the left hand side, easy to see if you remove the trim panel above the pedals)?

If not, the heater bypass valve is not closing off the coolant supply. Could be a faulty HBV itself or an issue with the vacuum supply to it.

How cold are the vents blowing?
