PURPOSE: A door assembly for converting blow mode for vehicle air conditioning system is provided, in which the door assembly consists of a rotating unit and a shield unit, to thereby simplify the structure of the assembly and reduce cost. CONSTITUTION: A door assembly comprises a rotating unit(30) having a rotation axis(32), and a pair of rotating wheels(34) attached to both ends of the rotation axis and which has a plurality of stoppers(35) formed along the outer periphery of the rotating wheel; a flexible shield unit(40) having a shield section(42) with a plurality of stopper holes(42a) formed at both ends of the shield section for insertion of stoppers formed at the rotating wheel, and an opening(44) formed at the intermediate portion of the shield section; and a pair of guide channels positioned adjacent to the rotating wheel of the rotating unit within a blower case, and which guide the flexible shield unit in a specific direction to move along a predetermined orbit at a position deviated from the rotating wheel. The flexible shield unit is interlocked with the rotating unit such that the stopper and the stopper hole are coupled/separated to/from each other in accordance with the rotation of the rotating unit.
