DIAGNOSIS & TESTING

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.
• 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.

Downloaded from www.Manualslib.com manuals search engine CAUTION:
The A/C accumulator and the A/C liquid line must be replaced if an internal failure of the A/C com-
pressor has occurred. Failure to replace the A/C accumulator and the A/C liquid line can cause
serious damage to the replacement A/C compressor.
NOTE :
When replacing multiple A/C system components, determine how much oil should be removed from the new A/C
compressor.
NOTE :
Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failure
to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.1. Evacuate the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Conditioning).
2. Disconnect the A/C compressor electrical connector.
3. Remove the engine drive belt (See Drive Belt Removal & Installation in Section 02 Engine).
4. Remove the intake manifold (See Intake Manifold Removal & Installation in Section 02 Engine).
5. Remove the A/C compressor line bolt (1) from the A/C compressor.
(Tighten: A/C compressor line bolt to 20 N·m)
NOTE: After removing the A/C lines, plug the A/C
lines to prevent any debris from entering the A/C
system.
6. Loosen the A/C compressor bracket bolt connecting the A/C compressor and bracket. (Tighten: A/C compressor bracket bolt to 40 N·m)

Description
Available occupant restraints for this vehicle include both active and passive types. Active restraints are those which
require the vehicle occupants to take some action to employ, such as fastening a seat belt; while passive restraints
require no action by the vehicle occupants to be employed.
Active Restraints
•Front Seat Belts
• Rear Seat Belts
Passive Restraints
• Driver Airbag
• Passenger Airbag
• Seat Belt Tensioners
Operation
Active Restraints
The primary passenger restraints are the seat belts. Seat belts are referred to as an active restraint because the
vehicle occupants are required to physically fasten and properly adjust these restraints in order to benefit from them.
Passive Restraints
The passive restraints are referred to as a supplemental restraint system because they were designed and are
intended to enhance the protection for the occupants of the vehicle only when used in conjunction with the seat belts.
They are referred to as passive restraints because the vehicle occupants are not required to do anything to make
them operate; however, the vehicle occupants must be wearing their seat belts in order to obtain the maximum safety
benefit from the supplemental restraint system.
The supplemental restraint system electrical circuits are continuously monitored and controlled by a microprocessor
and software contained within the Restraints Control Module (RCM). An airbag indicator in the instrument cluster
illuminates for about seven seconds as a bulb test each time the ignition switch is turned to the ON or START posi-
tions. Following the bulb test, the airbag indicator is turned ON or OFF by the RCM to indicate the status of the
supplemental restraint system. If the airbag indicator comes ON at any time other than during the bulb test, it indi-
cates that there is a problem in the supplemental restraint system electrical circuits. Such a problem may cause
airbags not to deploy when required, or to deploy when not required.
Deployment of the supplemental restraints depends upon the angle and severity of an impact. When an impact is
severe enough, the microprocessor in the RCM signals the inflator of the appropriate airbag units to deploy their
airbag cushions. The front seat belt tensioners are provided with a deployment signal by the RCM in conjunction with
the front airbags.
