An air conditioning system for a vehicle includes a first air path formed within an air duct, and a second air path formed within the air duct. The air conditioning system also includes an air mixing damper for adjusting a first amount of air, which flows within the first air path, and a second amount of air, which flows within the second air path. The air mixing damper includes a plurality of convex portions, and a plurality of concave portions, each of which concave portions is positioned between adjacent pairs of the plurality of convex portions. The air conditioning system also includes a drive mechanism for driving the air mixing damper. The drive mechanism includes a first gear engaging a portion of the plurality of convex portions and a portion of the plurality of concave portions. The drive mechanism also includes a shaft coupled operationally to the first gear, and an end of the shaft is positioned outside the air duct. Moreover, the drive mechanism includes a second gear coupled operationally to the end of the shaft, and a sector gear engaging the second gear. For example, a gear ratio of the second gear to the sector gear may be greater than or equal to 3:1.
