1. An air-conditioner for a vehicle, comprising: a first air inlet for selectively introducing outside air from outside a passenger compartment of a vehicle and inside air from inside the passenger compartment;a second air inlet for selectively introducing the inside air and the outside air;a first switching damper for switching opening and closing of the first air inlet;a second switching damper for switching opening and closing of the second air inlet;a first passage communicating with the first air inlet;a second passage communicating with the second air inlet, the second passage being divided by a partition from the first passage along an entire length of the second passage from the second inlet;an evaporator and a heater core disposed in the first and second passages in the named order as viewed from the first and second air inlets;a defrost outlet disposed at an upper front portion of an instrument panel of the vehicle;right and left side defrost outlets disposed at opposite right and left sides of the instrument panel;right and left side vent outlets disposed at opposite right and left sides of the instrument panel;a pair of laterally juxtaposed center vent outlets disposed at a central portion of the instrument panel that directs airflow toward a face of a vehicle occupant;right and left heat outlets disposed at a floor panel of the vehicle;a side vent/DEFROST switching damper disposed downstream of the heater core; anda center vent/heater switching damper disposed in the second passage downstream of the heater core,wherein the side vent/DEFROST switching damper is configured to switchably operate in one of a defrost/side vent position in which the first passage is connected with each of the defrost outlet, the right and left side defrost outlets and the right and left side vent outlets, and a side vent position in which the first passage is connected with only the right and left side vent outlets,wherein the center vent/heater switching damper is configured to switchably operate in one of a center vent position in which the second passage is connected with only the pair of laterally juxtaposed center vent outlets, a heater position in which the second passage is connected with only the right and left heat outlets, and a center vent/heater position in which the second passage is connected with both the pair of laterally juxtaposed center vent outlets and the right and left heat outlets,wherein the air-conditioner is configured to operate in plural different modes, including at least a first mode which simultaneously positions: the first switching damper to direct the outside air through the first air inlet into the first passage to be conditioned into a first conditioned air by the evaporator and the heater core,the side vent/DEFROST switching damper to the defrost/side vent position thereby directing the first conditioned air from the first passage to the defrost outlet, the right and left side defrost outlets and the right and left side vent outlets toward windowpanes of the vehicle,the second switching damper to direct the inside air through the second air inlet into the second passage to be conditioned into a second conditioned air by the evaporator and the heater core, andthe center vent/heater switching damper to the center vent/heater position thereby directing the second conditioned air from the second passage to the pair of laterally juxtaposed center vent outlets and the right and left heat outlets into the passenger compartment. 2. The air-conditioner according to claim 1, further comprising: a first fan disposed in the first passage and located between the first air inlet and the evaporator; anda second fan disposed in the second passage and located between the second air inlet and the evaporator,wherein the first fan and the second fan are individually supported on respective driving shafts. 3. The air-conditioner according to claim 1, wherein the evaporator is mounted to tilt in a backward direction of the vehicle, and the tilted evaporator includes a lower half disposed in the first passage and an upper half disposed in the second passage. 4. The air-conditioner according to 1, wherein the evaporator is mounted to tilt in the backward direction of the vehicle, and the tilted evaporator includes a lower half disposed in the first passage and an upper half disposed in the second passage,wherein the heater core is mounted to tilt in a backward direction of the vehicle and parallel to the evaporator, and the tilted heater core includes a lower half disposed in the first passage and an upper half disposed in the second passage. 5. The air-conditioner according to claim 4, further comprising: a first fan disposed in the first passage and located between the first air inlet and the evaporator; anda second fan disposed in the second passage and located between the second air inlet and the evaporator,wherein the first fan and the second fan are individually supported on respective driving shafts. 6. The air-conditioner according to claim 4, wherein the side vent/DEFROST switching damper is disposed above the heater core, andwherein the center vent/heater switching damper disposed in the second passage is located rearwardly of the evaporator upper half as viewed in a longitudinal direction of the vehicle. 7. The air-conditioner according to claim 6, further comprising: a first fan disposed in the first passage and located between the first air inlet and the evaporator; anda second fan disposed in the second passage and located between the second air inlet and the evaporator,wherein the first fan and the second fan are individually supported on respective driving shafts.
