The heating and ventilation system includes the following:
- Blower motor
- Evaporator core housing
- Heater core housing
- Heater core
The heating and ventilation system has the following features:
- System controls the temperature and reduces the relative humidity of the air inside the vehicle during A/C operation
- System 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
- The temperature is then regulated by reheating a portion of the air and blending it with the remaining cool air to the desired temperature
- The temperature blending is varied by the air temperature control doors, which regulate the amount of airflow through and around the heater core, where it is then mixed and distributed
