ABSTRACT OF THE DISCLOSURE An air induction system for an automotive air- conditioner has an air switching housing connected to the suction opening of a blower casing. The housing is provided with a fresh outdoor air induction opening formed in the top wall opposing the suction opening, and a recirculated indoor air induction opening formed in a side wall adjacent to the top wall. An air-switching door is provided for selectively opening and closing the outdoor air induction opening and the indoor air opening. The air-switching door is foldable substantially at its mid portion so that, when the door closes the indoor air induction opening, it is folded to provide a small effective area, while, when it closes the outdoor air induction opening, it is extended to provide a large effective area. The system further has auxiliary indoor air induction openings formed in other side walls and an accordion-type shutter for selectively closing and opening the auxiliary indoor air induction opening. The air switching door and the accordion-type shutter are operatively connected such that, when the door opens the outdoor air induction opening and closes the indoor air opening, the shutter closes the auxiliary indoor air induction openings.
