1. An air conditioner for a vehicle, which includes an air conditioning case having an air passage formed therein and air outlets which include a defrost vent and a face vent, and a heat exchanger for cooling and a heat exchanger for heating, which are provided in the air passage of the air conditioning case, the air conditioner comprising:
a temperature door arranged between the heat exchanger for cooling and the heat exchanger for heating in order to adjust a degree of heating of cold air, which passed the heat exchanger for cooling, by the heat exchanger;
a cold air passage through which cold air that passed the heat exchanger for cooling bypasses the heat exchanger for heating;
a warm air passage through which the cold air that passed the heat exchanger for cooling passes the heat exchanger for heating;
a cold air guide unit for guiding the cold air downstream of the heat exchanger for cooling; and
a warm air guide unit for guiding the warm air downstream of the heat exchanger for heating;
wherein the air passage in the air conditioning case is partitioned into an upper passage and a lower passage by a partition wall, and
wherein the warm air guide unit changes a flow path of the air, which directs a flow path of the air toward the face vent after passing the heat exchanger for heating, to be guided to the defrost vent;
wherein a baffle is formed downstream of the heat exchanger for heating in the warm air passage;
wherein the warm air guide unit extends integrally from an end portion of the baffle.
