An active grille shutter system comprising a controller, a sensor provides a freeze signal to the controller when a temperature is near or below freezing, and an electric motor that opens and closes a plurality of vanes. The motor receives a low current signal from the controller to operate the system at a first torque level and receives a high current signal to operate the system at a second torque level when the controller receives the freeze signal. A precipitation signal from the windshield wiper system of the vehicle is provided to the controller to provide an indication that there is precipitation present in the vehicle environment. The controller may provide the high current signal to the motor only when the freeze signal and the precipitation signal are provided to the controller. A method is also provided for operating the system.
