The obvious is often missed, on this occasion the temp knob is in mid position.Forgive me if I appear condescending but you know that if the temperature knob is turned either hard left or right, the recirc light comes on together with the aircon? Think I got that right.
That worked a treat, thanksHave you tried turning it all off via the tiny finger push top left on the panel, then on again after waiting a while?
