ABSTRACT:
An automotive air conditioning system has a DEMIST mode which is operative at least in VENT or BI-LEVEL modes for switching conditioned air flow from an upper vent air outlet to a defroster nozzle. In the DEMIST mode, the temperature of air discharged through the defroster nozzle is controlled according to a previously selected, desired temperature so that the air discharged through the defroster nozzle can perform defrosting or demisting of the front windshield as well as conditioning of the temperature in the vehicle cabin. A blower speed control system responds to selection of the DEMIST mode by temporarily adjusting the variation range of the blower speed to not less than a medium speed for a given time period. This helps speed the defrosting or demisting effect of the air conditioning system.
