Typical active grille shutter vanes meet the frame at either end, with a small clearance between the parts, to avoid the parts binding together. This invention adds a set of soft flaps, which are molded in a two-shot process, to allow the vanes to seal against the frame while closed but sit free of the frame while open. This clearance is accomplished by adding a stepped wall to the frame component, to create an interference between the vane flaps while turning to the closed position, causing the flaps to be deflected in a gradual manner, so the actuator motor is not taxed with a sudden increase in required torque.
