The present invention relates to a heater unit for the automobile air conditioner. The heater unit comprises a sensor group consisting of a plurality of sensors, mode selecting means for selecting one from at least two D/F modes above-mentioned, and control means for obtaining "target blowout tempeature (Tm)" based on input data from said sensor group and for selecting one out of said two D/F modes in which the rate of air through said foot outlet is greater, in the case where ambient air temperature taken by said sensor group is lower than the specified point corresponding thereto. In virtue of this, it contributed to improving air heating performance with window clouding prevented, in accordance with in- and out-car conditions.
