PURPOSE: A control method for a blower motor of a vehicle air conditioner is provided to prevent a driver from mis-hearing alarm sounds due to the operational noise of a blower fan. CONSTITUTION: A control method for a blower motor of a vehicle air conditioner comprises steps of: determining whether the blower motor of a vehicle air conditioner is in operation(S10), determining whether the operating condition of the blower motor is the condition where a safe driving assistant device including an alarm sound generator is operated(S20), determining whether the current voltage applied to the blower motor is higher than a first threshold voltage(S30), reducing the voltage applied to the blower motor to a second threshold voltage(S40), determining whether the operation of the safe driving assistant device is released(S50), and returning the voltage applied to the blower motor to the voltage before the determination of the safe driving assistant device operating condition(S60).
