Heating and Ventilation
The heating and defrosting system has the following features
- Delivers heated or cooled air to maintain the vehicle interior temperature and comfort level.
- A/C operation; reduces the relative humidity of the air inside the vehicle.
- The blower motor draws outside air or recirculates air from within the vehicle.
- The temperature blending is varied by the air temperature control door, which regulates the amount of air that flows through and around the heater core, where it is then mixed and distributed.
Heater Core Housing
The heater core housing contains the following components
- Heater core
- Air temperature control door
- Panel air flow control door
- Defrost/floor air flow control door
- A/C evaporator core
The heater core consists of fins and tubes arranged to extract heat from the engine coolant and transfer the heat to air passing through the heater core housing.
Blower Motor
The blower motor pulls air from the air inlet and forces it into the heater core housing where it is mixed and distributed.
