PURPOSE:To improve the comfortableness of the environmental conditions inside a vehicle by reducing the quantity of suckedout air inside the vehicle when a conditioning means is set in the cooling mode, however a cooling portion has not be cooled yet. CONSTITUTION:With an air conditioner set in the auto-mode and an air conditioner switch 60 off, a relay 46 carries no current so that the contact 46a thereof is open. Regardless of the position of a program switch 20 set among 200- 230, the current is restricted to run to a fan motor 5a via a friction switch 20b2, however, the current through the series connection of resistances 38a-38d is sent to the fan motor 5a so that the quantity of supply air is controlled to the minimum. Even if the air conditioner switch 60 remains off and a cooler core 6 has not be cooled yet in spite of a demand for cooling, uncomfortableness may be prevented since high temperature air will not be supplied inside the vehicle. |
