DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
System Airflow: Panel
2010 Mercury Mariner Hybrid, AWDSECTION Panel
WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
When PANEL is selected:
- the Recirc request button is enabled. If the Recirc request button is selected (indicator ON), the air inlet door actuator positions the air inlet door to close off outside air from entering the passenger compartment. If the Recirc request button is not selected (indicator OFF), the air inlet door actuator positions the air inlet door to admit only outside air into the passenger compartment.
- the floor door actuator positions the floor door in the closed position, and the panel/defrost door actuator positions the panel/defrost door to direct airflow to the instrument panel A/C registers. The system will allow some airflow through the floor ducts.
- temperature control can be adjusted by directing the airflow through and around the heater core. Only when the A/C compressor operation has been selected by pressing the A/C request switch (indicator ON) can the airflow temperature be cooled below that of the ambient (outside) air temperature.
- the A/C request button is enabled. When the A/C request button is selected (indicator ON), the A/C compressor will operate if the outside air temperature is above approximately 2°C (35°F). When the A/C request button is not selected (indicator OFF), the A/C compressor will not operate and the air cannot be cooled below the outside temperature.
- the blower motor is ON.
