WARNING: This page is about a different car, the 2016 Ford Transit-350 HD, 2016 Ford Transit-350, 2016 Ford Transit-250, and 2016 Ford Transit-150. However, it is still accessible from the selected car via links, so may be relevant.

The HVAC control module is not on the CAN and does not set Diagnostic trouble Codes (DTCs).

The blower motor speed switch is mounted in the HVAC control module and controls blower motor speed by adding or bypassing resistors in the blower motor resistor in all modes except OFF. The blower motor speed switch is an integral part of the HVAC control module and cannot be serviced separately.

The temperature control switch adjusts the discharge air temperature. Movement of the temperature knob from cool to warm causes the temperature door to move. The position of the temperature door determines the discharge air temperature. The temperature control selector is an integral part of the HVAC control module and cannot be serviced separately.

The airflow mode setting adjusts the discharge air outlet location. Each airflow mode selector icon causes a corresponding movement of the airflow mode doors and determines the discharge air outlet location. The airflow mode selector knob is an integral part of the HVAC control module and cannot be serviced separately.

The A/C button determines A/C compressor operation, except when the temperature selector is set to MAX A/C or the airflow mode selector is in defrost mode. The A/C button is an integral part of the HVAC control module and cannot be serviced separately.

The recirculated air request button can be activated in any mode except defrost and MAX A/C. The recirculated air request button is an integral part of the HVAC control module and cannot be serviced separately.
