Description
This vehicle is equipped with a common HVAC housing assembly. The system combines air conditioning, heating,
and ventilating capabilities in a single unit housing mounted under the instrument panel. The driver can choose the
following functions from HVAC control panel:
•The inside temperature
• The speed of the blower
• Five different modes of operation
• A/C compressor clutch operation
• Recirculation door position
NOTE :
To maintain the performance level of the heating, ventilation and air conditioning (HVAC) system, the engine cooling
system must be properly maintained. Any obstructions in front of the radiator or A/C condenser will reduce the per-
formance of the A/C and engine cooling systems.

Engine coolant is delivered to the heater core through heater hoses. With the engine idling at normal operating tem-
perature, set the temperature control knob in the full hot position, the mode control switch knob in the floor heat
position, and the blower motor switch knob in the highest speed position. Using a test thermometer, check the tem-
perature of the air being discharged at the HVAC housing floor outlets. Compare the test thermometer reading to the
heater performance chart.

Both of the heater hoses should be hot to the touch. The coolant return heater hose should be slightly cooler than
the coolant supply heater hose. If the return hose is much cooler than the supply hose, locate and repair the engine
coolant flow obstruction in the cooling system.
Obstructed Coolant Flow
Possible locations or causes of obstructed coolant flow:
• Pinched or kinked heater hoses.
• Improper heater hose routing.
• Plugged heater hoses or supply and return ports at the cooling system connections.
• A plugged heater core.
Mechanical Problems
Possible locations or causes of insufficient heat:
•An obstructed cowl air intake.
• Obstructed heater system outlets.
• A blend door not functioning properly.
• Trapped air in system.
Temperature Control
If the heater outlet air temperature cannot be adjusted with the temperature control knob(s) on the A/C heater control
panel, the following could require service:
•The A/C heater control panel.
• The blend door.
• The blend door cable.
• Improper engine coolant temperature.

Evaporator
Description
The evaporator core is located in the HVAC housing, under the instrument panel. The evaporator coil is positioned in
the HVAC housing so that all air that enters the housing must pass over the fins of the evaporator before it is dis-
tributed through the system ducts and outlets. However, air passing over the evaporator core fins will only be con-
ditioned when the compressor is engaged and circulating refrigerant through the evaporator coil tubes.
Operation
Refrigerant enters the evaporator from the orifice tube as a low-temperature, low-pressure liquid. As air flows over
the fins of the evaporator, the humidity in the air condenses on the fins, and the heat from the air is absorbed by the
refrigerant. Heat absorption causes the refrigerant to boil and vaporize. The refrigerant becomes a low-pressure gas
before it leaves the evaporator. The evaporator core housing directs airflow from the blower motor through the evap-
orator 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).
Removal & Installation
1. Evacuate the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Conditioning).
2. Remove the expansion valve.
3. Remove the HVAC housing (See HVAC Housing Removal and Installation in Section 13 Heating & Air Condi-
tioning).
4. Remove the retaining bolts and screws.
5. Remove the evaporator core.
6. Installation is in the reverse order of removal.
Installation Notes:
• Lubricate new rubber O-ring seals with clean refrigerant oil and install them and new gaskets onto the refriger-
ant line fittings.
• Use only the specified O-rings as they are made of a special material for the R-134a system.
• Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
• Recharge the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Condition-
ing).
Condenser
Description
The condenser is located in the air flow in front of the engine cooling radiator. The condenser transforms the refrig-
erant from a gas into a liquid. It is attached to the vehicle with bolts and the A/C lines with fittings.
Operation
When the heat is removed from the refrigerant, it condenses. When the refrigerant leaves the condenser, it becomes
a high-pressure liquid refrigerant. The volume of air flowing over the condenser fins is critical to the proper cooling
performance of the air conditioning system. Therefore, it is important that there are no objects placed in front of the
radiator grille openings in the front of the vehicle or foreign material on the condenser fins that might obstruct proper
air flow. Also, any factory-installed air seals or shrouds must be properly reinstalled following radiator or condenser
service.

Downloaded from www.Manualslib.com manuals search engine Heater Core
Description
The heater core is located in the HVAC housing. The heater core is a heat exchanger made of rows of tubes with
fins and is positioned within the air distribution housing so that only the selected amount of air entering the housing
passes through the heater core before it is distributed through the heating-A/C system ducts and outlets. One end of
the heater core is fitted with a tank that includes the fittings for the heater core tubes. The heater core can only be
serviced by removing the HVAC housing from the vehicle.
Operation
Engine coolant is circulated through the heater hoses to the heater core at all times. As the coolant flows through the
heater core, heat is removed from the engine and is transferred to the heater core tubes and fins. Air directed
through the heater core picks up the heat from the heater core fins. The blend-air door allows control of the heater
output air temperature by regulating the amount of air flowing through the heater core. The blower motor speed con-
trols the volume of air flowing through the HVAC housing.
Removal & Installation
1. Drain the cooling system (See Cooling System Draining Procedure in Section 06 Cooling System).
2. Evacuate the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Conditioning).
3. Remove the HVAC housing assembly and place it on a workbench (See HVAC Housing Removal & Installationin Section 13 Heating & Air Conditioning).
4. Remove the retaining bolts and clamps.
5. Remove the heater core.
6. Installation is in the reverse order of removal.
Installation Notes:
• Verify the cooling system is filled to proper specifications.
