Construction
-
The A/C unit consists of the following parts.
Operation
Air Mix Door Operation
-
The air mix door, installed in the A/C unit, controls HOT or COLD position, depending on the position of the temperature control dial. As a result, airflow distribution changes, and the airflow temperature is controlled.
Airflow Mode Door Operation
-
The airflow mode doors move to VENT, BI-LEVEL, HEAT, DEF/HEAT, or DEFROSTER position, depending on the position of the airflow mode selector dial. As a result, airflow mode changes.
