Abstract: The present invention relates to a blower unit of an air conditioner for a vehicle, which can enhance air-conditioning performance through uniform upper and lower pressure control since compensating and supplementing different air resistances between an upper scroll case and a lower scroll case. The blower unit of the two-layered air conditioner for a vehicle, which separates and blows indoor air and outdoor air, includes: a first scroll in which a first blower wheel is disposed and a first air passageway is formed; and a second scroll arranged below the first scroll, and having a second blower wheel and a second air passageway, wherein a diameter of the second blower wheel and a diameter of the first blower wheel are different from each other.
