Fresh/RECIRCULATION Control Lever

The fresh/recirculation lever mechanically operates a cable that opens or closes the fresh/recirculation mode door to fresh (outside) air. When in recirculation position, outside air is shut off and air from inside passenger compartment is recirculated through the blower motor to selected air outlets. See Fig 1 .
