Heating and Ventilation: Notes

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The heating and ventilation system has the following features:

Controls the temperature and, during A/C operation, reduces the relative humidity of the air inside the vehicle.
Delivers heated or cooled air to maintain the vehicle interior temperature and comfort level.
Cooling or heating can be adjusted to maintain the desired temperature.
Uses a reheat method to provide conditioned air to the passenger compartment.
All airflow from the blower motor passes through the A/C evaporator core.
Temperature blending is controlled by the temperature blend door(s), which regulate(s) the amount of air that flows through and around the heater core, where it is then mixed and distributed.
