PROBLEM TO BE SOLVED: To prevent the deterioration of visibility caused by the melting of snow adhered to a windshield by air-conditioning air blown out of a defroster blow-out port when snow falls. SOLUTION: A bypass door bypassing a heater core and capable of supplying outside air to the DEF blow-out port is provided in an air conditioner. In the case that snow fall is detected when the inside of a cabin is heated while the windshield is defogged (Step 102, Steps 110, 112), an air-conditioning ECU opens the bypass door based on vehicle speed v and an outside air temperature Ta, and drives a fan motor for sucking outside air blown out of the DEF blow-out port (Steps 114-130). Thus, by blowing out outside air from the DEF blow-out port to the windshield, the melting of snow adhered to the windshield can be prevented. COPYRIGHT: (C)2009,JPO&INPIT
