Grille Shutters
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The grille shutters are several "slats" or "blinds" connected to one another by a linkage system. One of the individual grille shutters is fixed to the grille shutter actuator. When the grille shutter actuator moves, it moves the attached shutter which causes the other linked shutters to move. The individual grille shutters are not available for service separately, they are serviced with the grille shutter assembly.
