1. A method of controlling an air blowing apparatus, the method comprising:
determining whether there is precipitation through a rain sensor by a controller;
determining whether the air blowing apparatus is in an automatic mode in a precipitation condition by the controller;
determining a vehicle speed when the air blowing apparatus is in the automatic mode in the precipitation condition; and
setting power and a spray angle of the air blowing apparatus by comparing a measured rainfall received from the rain sensor to a stored rainfall by the controller,
wherein setting the power and the spray angle of the air blowing apparatus includes compensating the spray angle and a spray amount of the air blowing apparatus by measuring a flow speed and a flow angle of rainwater through the rain sensor by the controller.
 
16. The method of claim 1, wherein setting the power and the spray angle of the air blowing apparatus further comprises:
measuring the flow speed and the flow angle of rainwater on a windshield glass through the rain sensor; and
controlling the power of the air blowing apparatus in accordance with the measured flow speed and flow angle of the rainwater.
