WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. 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 main (front) 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/mode control between COOL/ROOF and WARM/FLOOR causes a corresponding movement of the temperature blend door to mix air flowing through and around the auxiliary heater core and also causes a corresponding movement of the mode door to the ROOF and FLOOR positions.
