The method includes a time measuring step for measuring the time taken for the control louver to be driven a predetermined amount, and a driving step for comparing the measured time obtained at the time measuring step with a reference time and increasing a drive force for the control louver when the measured time is more than the reference time while driving the control louver by a normal drive force when the measured time is not more than the reference time.
