Abstract
An air distribution housing in an automotive air conditioning system includes spaced wall portions forming an air passage for flow of conditioned air into the passenger compartment of a motor vehicle; each of the wall portions having pins directed internally of the wall portions without forming openings therethrough and including distal ends thereon inserted into a tubular end portion of the valve member for pivotally supporting the valve member within the air passage without penetrating through the spaced wall portions so as to prevent air leakage and resultant noise from the air distribution housing. A method of assembly of the air distribution housing includes the steps of providing two separate housing parts with integrally formed pins on the inner surfaces thereof; providing a valve door with a pivot tube on one end thereof; vertically locating one end of the tube on one of the pins; thereafter joining the housing parts to locate the other pin in the other end of the pivot tube.
