An air conditioner system for vehicles which includes at least two connecting passages interconnecting a main duct of the front-seat air conditioner unit and an air mix chamber in a duct of the rear-seat blower unit. Air mix doors are disposed in the connecting passages to adjust the amount of air introduced from the main duct through the respective connecting passages to the air mix chamber. One of the connecting passages has an inlet opening to the main duct between an evaporator and a heater core disposed in the main duct whereas the other connecting passage has an inlet opening to the main duct downstream of the heater core. Thus the amount and temperature of the air blown into a rear-seat part of the passenger compartment can be controlled independently of the temperature and the amount of the air blown into the front-seat part. With the connecting passages thus arranged, the main duct is simple in structure and hence can be manufactured more economically.
