Claim 18:
19. The method of claim 16, further comprising:
determining whether the flow speed of the rainwater measured by the rain sensor is less than a first reference value and whether the flow angle of the rain water is less than a second reference value by the controller;
determining whether the flow speed and flow angle of the rainwater is less than a third reference value by the controller when the flow speed of the rainwater is less than the first reference value and the flow angle of the rainwater is less than the second reference value;
measuring external information of the vehicle when the flow speed and the flow angle of the rainwater are the third reference value by the controller;
determining whether the windshield glass is in a dew point saturation state base on the measured external information by the controller; and
operating a glass heater and a blow heater and controlling the spray angle and a discharge amount of the air blowing apparatus to a maximum by the controller when the windshield glass is in the dew point saturation state.
