When a difference in opening angle of an air-mixing door between a target position and an actual position is larger in value than a width of an insensitive band area, a mixing door actuator is driven to a heating side or a cooling side depending on the amount of the difference so as to have the air-mixing door reach its target position in a condition in which the insensitive band area is eliminated. When the difference is smaller than the predetermined band width, i.e., when a drive position of the mixing door actuator is in the insensitive band width, this band width is effected so that the mixing door actuator is stopped in operation to stabilize the operation.
