An air conditioner for an automotive vehicle having (1) a duct having at its one end an air inlet, at the upper part of its other end a ventilation outlet, and at the lower part of its other end a floor outlet linked to a defroster outlet; (2) a blower disposed at the air inlet for introducing air into the duct; (3) an evaporator disposed downstream of the duct for cooling the air introduced by the blower; (4) a heater core disposed downstream of the evaporator whose upper side is provided with a first bypass for bypassing the cooled air from the evaporator; (5) an air mixing door disposed upstream of the heater core for adjusting the amount of air passing through the heater core; (6) an air mixing chamber disposed downstream of the heater core and first bypass for mixing the air from the first bypass and heater core, the ratio of the air depending on the angle of the air mixing door; (7) a second bypass disposed between the heater core and the floor outlet for introducing part of the heated air from the heater core directly into the floor outlet; and (8) a smaller door located at the heater core for adjusting the amount of heated air passing through the second bypass, whereby the air temperature at the floor outlet is higher by a constant amount from that at the ventilation outlet.
