A method for manufacturing an improved air damper for a motor vehicle temperature control unit includes a first machining process for injection-molding a sealing section to be formed into a hollow shape. One end of the sealing section is simultaneously injected onto a lower surface of a base member. In a second machining process, the other end of the sealing section is slip-fitted onto the upper surface of the base member and mechanically affixed thereto. To this end, the sealing section preferably has openings which may be positioned over corresponding fixing pins extending from the upper surface of the base member. The fixing pins may then be folded down, for example, by heat welding to lock the fixing pins over the sealing section and thereby form a hollow member. The sealing section further includes a sealing lug for abutting a housing portion of the temperature control unit, such as an interior wall of an air duct.
