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.

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.
• The blend door actuator(s).
• The wire harness circuits for the A/C heater control or the blend door actuator(s).
• The blend door(s).
• Improper engine coolant temperature.
A/C Compressor Noise Testing
When investigating an A/C system related noise, you must first know the conditions under which the noise occurs.
These conditions include: weather, vehicle speed, transaxle in gear or neutral, engine speed, engine temperature,
and any other special conditions. Noises that develop during A/C operation can often be misleading. For example:
what sounds like a failed bearing, may be caused by loose bolts, nuts, mounting brackets or a loose compressor
assembly.
NOTE :
The A/C compressor must be replaced if any unusual noise is heard from the compressor itself.
NOTE :
Drive belts are speed sensitive. At different engine speeds and depending upon drive belt tension, drive belts can
develop noises that are mistaken for an A/C compressor noise. Improper drive belt tension can cause a misleading
noise when the compressor is operating at maximum displacement, which may not occur when the compressor is at
minimum displacement.
1. Select a quiet area for testing.
2. Duplicate the complaint conditions as much as possible.
3. Turn the A/C system On and Off several times to clearly identify any compressor noise.
4. Listen to the A/C compressor while it is operating at maximum and minimum displacement.
5. Probe the A/C compressor with an engine stethoscope or a long screwdriver with the handle held to your ear to better localize the source of the noise.
6. To duplicate high-ambient temperature conditions (high head pressure), restrict the air flow through the A/C con- denser. Install a manifold gauge set or a scan tool to ensure that the discharge pressure does not exceed 2600
kPa.
7. Check the condition of the accessory drive belt. NOTE: The A/C compressor must be replaced if the drive hub is broken or if the compressor shaft does not
rotate smoothly.
8. Check the compressor hub and pulley and bearing assembly. Ensure that the hub and pulley are properly aligned and that the pulley bearing is mounted securely to the A/C compressor.
9. Check the refrigerant system plumbing for incorrect routing, rubbing or interference, which can cause unusual noises. Also check the refrigerant lines and hoses for kinks or sharp bends that will restrict refrigerant flow, which
can cause noises.
10. Loosen all of the compressor mounting hardware and retighten. CAUTION: Do not run the engine with a vacuum pump in operation or with a vacuum present within the
A/C system. Failure to follow this caution will result in serious A/C compressor damage.
11. If the noise is from opening and closing the high pressure relief valve, recover, evacuate and recharge the refrig- erant system. If the high pressure relief valve still does not seat properly, replace the A/C compressor.

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.

Description
The Instrument Cluster (IC) is located in the instrument panel directly in front of the driver. The IC is used to inform
the driver of specific vehicle information. The IC uses indicator lamps and gauges to warn the driver of potentially
critical operating conditions.
Operation
The Instrument Cluster (IC) uses hard wired inputs from various sensors and switches. The sensors and switches are
located throughout the vehicle. The IC displays the following gauges:
•Speedometer - The IC displays the vehicle speed as determined by the Engine Control Module (ECM).
• Tachometer - The IC displays the engine speed as determined by the Engine Control Module (ECM).
• Temperature Gauge - The IC displays the engine coolant temperature as determined by the Engine Control
Module (ECM).
• Fuel Gauge - The IC displays the amount of fuel in the fuel tank as determined by the fuel level sensor.
