An actuation mechanism including a motor having a first motor output gear and a second motor output gear is provided, the motor defining a common axis of rotation for the first and second motor output gears. The actuation mechanism also includes a pair of gearboxes positioned on opposed ends of the motor. The actuation mechanism further includes a first arm adapted to mechanically cooperate with the first gearbox and a second arm adapted to mechanically cooperate with the second gearbox. The rotor of the motor slides along the common axis of rotation. The rotor is configured to be axially movable between a first position where the rotor engages the first gearbox to rotatably actuate the first arm and a second position where the rotor engages the second gearbox to rotatably actuate the second arm.
