ABSTRACT:
A base mode is set at a face mode or foot mode based on an external air temperature signal TAM detected by an external air temperature sensor. An automotive air conditioner includes a driver side air conditioning zone and a passenger side air conditioning zone. When the blow mode for the driver side air conditioning zone is set in the foot mode and the blow mode for the passenger side air conditioning zone is set in the face mode or vice versa, the blow mode which is identical to the base mode is maintained. The other blow mode is changed to a bilevel mode. This prevents frequent change in the base mode and avoids hunting.
