Abstract
A vehicle temperature control system includes a control assembly for directing a fluid actuating medium to selected ones of a plurality of door actuators to position a plurality of doors in selected modes of operation. The control assembly includes a valve housing defining a chamber, a fluid inlet passage and a plurality of opposed inlet cavities and outlet passages. A lever positioned slide valve is shiftable within the chamber. An array of control passages defined by the slide valve selectively place the inlet cavities in communication with the outlet passages. Seal members are disposed in each of the inlet cavities and outlet passages to insure that the fluid medium passes through the control passages. A mode selection lever engages the slide valve and also defines a cam surface for selectively actuating an air conditioner compressor switch.
