Heating and Ventilation

HEATING AND VENTILATION
The heating and defrosting system has the following features:
- Delivers heated or cooled air (with the A/C option) to maintain the vehicle interior temperature and comfort level.
- A/C operation (if equipped), reduces the relative humidity of the air inside the vehicle.
- The blower motor draws outside air or recirculates from within the vehicle air.
- 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.

Heater 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.

The heater core is located in the heater core and evaporator core housing.

Blower Motor
The blower motor pulls air from the air inlet and forces it into the heater core and evaporator core housing where it is mixed and distributed.

The blower motor is located on the bottom of the heater core and evaporator core housing below the glove compartment.

Heater Core and Evaporator Core Housing
The heater core and evaporator core housing directs airflow from the blower motor through the evaporator core and heater core. All airflow from the blower motor passes through the evaporator core. The airflow is then directed through or around the heater core by the temperature blend door(s). Manual systems use a single electric actuator-positioned temperature blend door to direct airflow through or around the heater core.

The heater core and evaporator core housing is mounted to the passenger compartment side of the dash panel.
