Fresh/Recirculated Air Selection Lever
When air selection lever is placed in the fresh air position, the fresh/recirculated air door moves to close the recirculation air inlet, leaving the outside air inlet open. When lever is moved to recirculate position, air door moves to cover the outside air inlet passage, leaving recirculated air inlet passage open.
Mode Selection Knob
Depending on position selected, air can be directed to both front and rear of passenger compartment. Selection capabilities include individual areas or a combination of windshield, upper body, knee and/or foot area airflow. Rear passenger air distribution is limited to foot area only.
Temperature Control Knob
When the temperature control knob is rotated fully counterclockwise, toward cool air position, the upper side of heater core is blocked by the blend-air door. As a result, all air from blower motor by-passes heater core, and flows into passenger compartment as cool air.
When temperature control knob is rotated fully clockwise, toward warm air position, blend-air door will block cool air path. Cool air from blower motor now passes through heater core for maximum heating.
With temperature knob in middle position, blend-air door will split air stream into two branches, one passing through the heater core and one by-passing the heater core. Various combinations of warm and cool air are available to meet various temperature requirements.
Blower Speed Lever
Blower speed is controlled by a multi-position, rotating blower switch.
