Picture 1 - The passenger kick panel holds the recirculated air door and actuator. A spring holds the door closed when no vacuum is applied to the actuator. (Note that the spring in the picture is a generic spring from a hardware store. )
The default vent mode uses outside air with the cowl vent open and the kick panel vent closed. When the temperature control lever is above and slightly left of the COLD position (recirculated air conditioning mode), vacuum is applied to both the cowl and kick panel vacuum actuators, closing the cowl fresh air door and opening the kick panel recirculation door. (More on vacuum lines and operation coming soon.)
Picture 2 - The back side of the kick panel has a small piece of jute padding glued to it and a large amount of putty/sealer to seal the panel to the car.
Picture 3 - The kick panel and actuator in place.
Picture 4 - The actuator cover in place. Please ignore the mis-matched and missing screws.
