An air conditioner system for a vehicle includes a rear-seat blower unit and a rear-seat blower unit which are connected only by at least two connecting passages. Thus the air conditioner system is simple in structure and hence easy to construct. Further, any existing front-seat air conditioner unit can be used without reconstruction. The temperature of the blown-off air is automatically adjusted in accordance with the difference between the temperature preset by the temperature setting means and the temperature detected by the rear-seat mode sensor so that the temperature in the rear-seat part of the passenger compartment can be controlled at passenger\s desire, independently of the temperature of the front-seat part.
