HEATING & AIR CONDITIONING

DESCRIPTION - HEATER AND AIR CONDITIONER

All vehicles are equipped with a common HVAC
housing assembly (Fig. 1). The system combines air
conditioning, heating, and ventilating capabilities in
a single unit housing mounted under the instrument
panel.

DESCRIPTION - COOLING SYSTEM

REQUIREMENTS

To maintain the performance level of the HVAC
system, the engine cooling system must be properly
maintained. The use of a bug screen is not recommended.
Any obstructions in front of the radiator or
condenser will reduce the performance of the air conditioning
and engine cooling systems.
The engine cooling system includes the heater core
and the heater hoses. Refer to Engine Cooling for
more information before the opening of, or attempting
any service to the engine cooling system.

DESCRIPTION - REFRIGERANT SYSTEM

SERVICE PORT

The two refrigerant system service ports are used
to charge, recover/recycle, evacuate, and test the air
conditioning refrigerant system. Unique service port
coupler sizes are used on the R-134a system, to
ensure that the refrigerant system is not accidentally
contaminated by the use of the wrong refrigerant
(R-12), or refrigerant system service equipment.

OPERATION

OPERATION - HEATER AND AIR CONDITIONER
The heater air conditioner are blend-air type systems.
In a blend-air system, a blend door controls the
amount of unconditioned air (or cooled air from the
evaporator on models with air conditioning) that is
allowed to flow through, or around, the heater core. A
temperature control knob on the A/C Heater control
panel determines the discharge air temperature by
controlling an electric actuator, which moves the
blend door. This allows an almost immediate control
of the output air temperature of the system.
The mode control knob on the A/C Heater control
panel is used to direct the conditioned air to the
selected system outlets. Both mode control switches
use electric actuators to control the mode doors.
On all vehicles, the outside air intake can be shut
off by selecting the Recirculation Mode with the
mode control knob. This will operate a electric actuated
recirculation door that closes off the outside
fresh air intake and recirculates the air that is
already inside the vehicle.

The air conditioner for all models is designed for
the use of non-CFC, R-134a refrigerant. The air conditioning
system has an evaporator to cool and dehumidify
the incoming air prior to blending it with the
heated air. This air conditioning system uses a fixed
orifice tube in the liquid line near the condenser outlet
tube to meter refrigerant flow to the evaporator.
