At higher speeds, the shutters close to streamline airflow around the vehicle, reducing drag and improving fuel economy.

The fuse acts as the primary electrical safeguard for the AGS actuator motor. If the shutters become obstructed—often by road debris, ice, or snow—the actuator motor may draw excessive current while trying to force them open or closed. The fuse is designed to "blow" in these scenarios to prevent the motor from overheating or causing further electrical damage to the vehicle's computer systems.

When the engine is under high load or in hot weather, the shutters open to allow maximum airflow through the radiator. The Role of the AGS Fuse At higher speeds, the shutters close to streamline

The primary goal of the AGS system is to balance a vehicle's cooling needs with its aerodynamic efficiency: The fuse is designed to "blow" in these
