HVAC Module

The HVAC module integrates the temperature control, airflow mode selection, A/C request button, recirculated air request button and rear defog switch into a single unit.

The temperature control setting determines air temperature. Movement of the temperature control from COOL (blue) to WARM (red) causes a corresponding movement of the temperature blend door and determines the air discharge temperature that the air distribution system will maintain. The temperature control switch is an integral part of the HVAC module and cannot be installed separately.

The airflow mode setting determines discharge air location. Movement of the mode selector causes a corresponding movement of the airflow mode door actuators. The mode selector is an integral part of the HVAC module and cannot be installed separately.

The A/C request button determines A/C compressor operation, except when the mode selector is in the OFF, MAX or DEFROST mode. The A/C request button is an integral part of the HVAC module and cannot be installed separately.

The recirculated air request button determines air inlet source, except when the airflow mode selector is in the OFF, MAX or DEFROST mode. The recirculated air request button is an integral part of the HVAC module and cannot be installed separately.

The rear defog button signals activation of the heated backlight and heated mirrors. The rear defog button is an integral part of the HVAC module and cannot be installed separately.

The HVAC module is not equipped with self-test capabilities.
