PURPOSE:To remove the uncomfortable feeling for a driver on engine start by operating an adjusting member for the blown-out air stream for rear seat by the output of the judging means such as a thermoswitch for judging the heating capacity of a heater core. CONSTITUTION:When the temperature of cooling water exceeds 30 deg.C after engine start, a thermoswitch 8 is opened to close the contact of a relay 14, and a heater relay 13 is energized. If the temperature of cooling water is below 50 deg.C, the relay 13 is energized by the relay 14, but the operation of a program switch 12 is ineffective. Therefore, a blower 6 revolves at an exceedingly low speed, and the wind blowing capacity is small, and since a thermoswitch 9 is in closed state, a connecting duct is closed by a damper, and wind is supplied only from a front-seat blow-out port. When the temperature of cooling water exceeds 50 deg.C, also the switch 9 is opened, and the blowing capacity of the blower 6 is selected, and the energizing of a solenoid valve 5 is released, and the connecting duct is opened by the damper, and the warm-wind blow-out to a rear seat is started. |
