tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
CAUTION:
The air conditioning system of this vehicle uses refrigerant HFC-134a (R-134a).
None of refrigerant, compressor oil and component parts is interchangeable between two types of A / C:
one using refrigerant CFC-12 (R-12) and the other using refrigerant HFC-134a (R-134a).
Be sure to check which refrigerant is used before any service work including inspection and mainte-
nance. For identification between these two types, refer to the description in page 1B-2.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A / C installed in the vehicle being serviced.
Use of incorrect one will result in leakage of refrigerant, damage in parts or other faulty condition.
For basic servicing method of the air conditioning system that is not described in this section, refer to AIR CONDI-
TIONING BASIC MANUAL (99520-02130).

DIAGNOSIS OF ABNORMAL NOISE
There are various types of noise, ranging from those produced in the engine compartment to those from the pas-
senger compartment, also from rumbling noises to whistling noises.
ABNORMAL NOISE FROM COMPRESSOR
ConditionPossible CauseCorrection

During compressor operation, a
rumbling noise is heard
proportional to engine
revolutions.
Inadequate clearance in piston
area (piston or swash-plate).
Repair or replace compressor as
necessary.

A loud noise is heard at a certain
rpm, disproportionately to engine
revolution.
Loose or faulty V-belt.

Loose mounting bolts.
Adjust V-belt tension, or
replace belt.

Retighten mounting bolts.

A loud rattle is heard at low
engine rpm.
Loose compressor center bolt.
Retighten center bolt.

Replace compressor if it was
operated in this condition for a
long time.
ABNORMAL NOISE FROM MAGNETIC CLUTCH
ConditionPossible CauseCorrection

A rumbling noise is heard when
compressor is not operating.
Worn or damaged bearings.
Replace bearings.

A chattering noise is heard when
compressor is engaged.
Faulty clutch gap (excessive).

Worn clutch friction surface.

Compressor oil leaked from shaft
seal, contaminating the friction
surface.
Adjust clutch gap.

Replace clutch.

Replace compressor shaft oil
seal.
ABNORMAL NOISE FROM TUBING
ConditionPossible CauseCorrection

A droning noise is heard inside
vehicle, but not particularly
noticeable in engine
compartment.
Faulty tubing clamps.

Resonance caused by pulsation
from variations in refrigerant
pressure.
Reposition clamps or increase
the number of clamps.

Attach a silencer to tubing, or
modify its position and length.
ABNORMAL NOISE FROM CONDENSER
ConditionPossible CauseCorrection

Considerable vibration in
condenser.
Resonance from condenser
mounting stay and body.
Firmly insert a silencer between
condenser mounting stay and
body.

COMPRESSION SYSTEM DIAGNOSIS
Compressor troubles are mainly following three types: gas leakage, noise and insufficient pressure.
Compressor gas leakages in most cases develop from the shaft seal. When detecting gas leakage, always use
a leak tester. If a small amount of oil seeps out from the shaft seal, there is no necessity of replacing the seal. The
shaft seal has been designed to allow a small amount of oil to leak out for lubricating purpose. Thus, the shaft seal
should be replaced only when a large amount of compressor oil is leaking out or when gas leakage is discovered
by using gas tester.
In regard to noise and insufficient pressure, repairs should be made only after diagnosing the trouble properly.

ON-VEHICLE SERVICE
WARNING:
Should refrigerant HFC-134a (R-134a) strike your eye(s), consult a doctor immediately.

DO NOT USE YOUR HAND TO RUB AFFECTED EYE(S).
Instead, use quantities of fresh cold water to splash it over affected area to thus gradually raise its
temperature above the freezing point.

Obtain proper treatment as soon as possible from a doctor or eye specialist.
Should liquid refrigerant HFC-134a (R-134a) get on your skin, such affected part should be treated
in the same manner as when skin is frostbitten or frozen.
CAUTION:
None of refrigerant, compressor oil and component parts is interchangeable between two types of A / C:
one using CFC-12 (R-12) and the other using HFC-134a (R-134a).
(For identification between these two types, refer to page 1B-2).
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A / C installed in the vehicle being serviced.
Use of incorrect one will result in leakage of refrigerant, damage in parts or other faulty condition.
PRECAUTION
When servicing air conditioning system, the following rules must be observed.
PIPING

When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling nuts
and O-ring.

Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.

Keep internal parts of air conditioning free from moisture and dirt. When disconnecting any line from system,
install a blind plug or cap to the fitting immediately.

When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.

CAUTION:
None of refrigerant, compressor oil and component parts is interchangeable between two types of A / C:
one using CFC-12 (R-12) and the other using HFC-134a (R-134a).
For identification between these two types, refer to page 1B-2.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A / C installed in the vehicle being serviced.
Use of incorrect refrigerant or compressor oil will result in leakage of refrigerant, damage in parts or
other faulty condition.
PRECAUTION
When servicing the compressor, keep dirt or foreign material away from getting on or into the compressor parts
and system. Clean tools and a clean work area are important for proper service.
The compressor connection and the outside of the compressor should be cleaned before any ªOn-vehicleº repair
or before removal of the compressor. The parts must be kept clean at all times and any parts to be reassembled
should be cleaned with Trichloroethane, naphtha, kerosene or equivalent solvent and dried with dry air. Use only
lint free cloths to wipe parts.
The operations described are based on bench overhaul with compressor removed from the vehicle, except as
noted. They have been prepared in order of accessibility of the components.
When compressor is removed from the vehicle for servicing, the oil remaining in the compressor should be dis-
carded and new refrigerant oil added to the compressor.
Minor repair procedures may be done on the vehicle without discharging the system. Major repair procedures re-
quire that the system be discharged of refrigerant.
