System Airflow
WARNING: This page is about a different car, the 2003 Mercury Mountaineer and 2003 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The auxiliary climate control system has the following features:
- The auxiliary blower motor recirculates the air inside the vehicle. Outside air is not available to the auxiliary climate control system.
- Air is cooled and dehumidified by the auxiliary evaporator core only if the instrument panel mounted climate control assembly is adjusted to a position that requires A/C compressor (19703) operation.
- The temperature blend door and the air distribution door are controlled by electronic actuator motors (19E616).
- Movement of the auxiliary temperature control between COOL and WARM causes a corresponding movement of the temperature blend door to mix air flowing through and around the auxiliary heater core.
- Toggling of the auxiliary air distribution control between PANEL and FLOOR causes a corresponding movement of the air distribution door to direct airflow between the panel (headliner) registers and the floor duct.
