System Airflow Description - Electronic Automatic Temperature Control (EATC) System: Auto
WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
When AUTO is selected:
- The temperature control setting is manually set to the desired setting.
- The air inlet door actuator is automatically controlled by the HVAC module - electronic automatic temperature control (EATC) based on the temperature setting.
- The mode door actuators are automatically controlled by the HVAC module - EATC based on the temperature setting.
- The A/C compressor is automatically controlled by the HVAC module - EATC based on the temperature setting. The A/C compressor will not operate if the outside temperature is below approximately 2°C (35°F).
- the A/C request is controlled by the HVAC module - EATC based on the temperature settings. The A/C compressor will not operate if the outside air temperature is below 2°C (35°F). The A/C indicator automatically turns ON when the outside air temperature rises above 14°C (58°F) and automatically turns OFF when the outside air temperature falls below 11°C (51°F).
- The A/C request button and the RECIRC request button can be manually selected. When manually selected, the A/C inicator will not change state with changing outside air temperature.
- The blower motor is ON. The blower motor speed is automatically controlled by the HVAC module - EATC based on the temperature setting, but can be manually overridden.
