A grille shutter for a vehicle includes a frame, an actuator, a grille flap, and a grille shaft. The actuator includes a casing mounted on the frame, an electric motor received in the casing, an output member having a first end, a second end and a stop projection between the first and second ends, and stop members stationary relative to the casing. The stop members cooperate with the stop projection to limit rotation of the output member. The grille shaft is coupled to the output member and rotatably couples the grille flap to the frame.
