From the aircon/heater unit diagram there would appear to be a failure of the Air Mix door(s)...somehow. There are two such doors. 1 for pax side and 1 for Driver side. Both are electrically driven from the Auto Amp module.

Its a bit of a complicated air mix system. Perhaps someone else knows more?
