Heating and Ventilation: Notes
WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. 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 (if equipped), 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.
- System 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, if equipped.
- The temperature is then regulated by reheating a portion of the air and blending it with the remaining cool air to the desired temperature.
- Temperature blending is varied by the temperature blend door(s), which regulate(s) the amount of air that flows through or around the heater core, where it is then mixed and distributed. Dual-zone Electronic Automatic Temperature Control (EATC) vehicles use 2 separately actuated temperature blend doors to allow for separate temperatures to be selected for the driver and passenger sides of the vehicle. Electronic Manual Temperature Control (EMTC) vehicles use a single temperature blend door.
