After connecting line, perform leak test and make sure that there is no leakage from connections.
When the gas leaking point is found, disconnect that line and replace the O-ring. Then tighten con-
nections of seal seat to the specified torque.
Precautions for Servicing CompressorAJS0013Z

Plug all openings to prevent moisture and foreign matter from entering.

When the compressor is removed, store it in the same position as it is when mounted on the car.

When replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compres-
sor” exactly. Refer to AT C - 2 7 , "
Maintenance of Lubricant Quantity in Compressor" .

Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with lubri-
cant, wipe it off by using a clean waste cloth moistened with thinner.

After compressor service operation, turn the compressor shaft by hand more than five turns in
both directions. This will equally distribute lubricant inside the compressor. After the compressor
is installed, let the engine idle and operate the compressor for one hour.

After replacing the compressor magnet clutch, apply voltage to the new one and check for usual
operation.
Precautions for Service EquipmentAJS00140
RECOVERY/RECYCLING EQUIPMENT
Be certain to follow the manufacturer’s instructions for machine operation and machine maintenance. Never
introduce any refrigerant other than that specified into the machine.
ELECTRONIC LEAK DETECTOR
Be certain to follow the manufacturer’s instructions for tester operation and tester maintenance.

PRECAUTIONS

Precautions for Leak Detection DyeAJS00141

The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.

Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.

The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to (J-
41995) pin-point refrigerant leaks.

For your safety and your customer′s satisfaction, read and follow all manufacture′s operating instructions
and precautions prior to performing the work.

A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal
should only be repaired after confirming the leak with an electronic refrigerant leak detector (J-41995).

Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis
during a future service.

Do not allow dye to come into contact with painted body panels or interior components. If dye is spilled,
clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period
of time cannot be removed.

Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).

Do not use more than one refrigerant dye bottle (1/4 ounce /7.4 cc) per A/C system.

Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Do not use
HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system or CFC-12 (R-12) leak detector dye
in HFC-134a (R-134a) A/C system or A/C system damage may result.

The fluorescent properties of the dye will remain for over three (3) years unless a compressor malfunction
occurs.
IDENTIFICATION
NOTE:
Vehicles with factory installed fluorescent dye have a green label.
Vehicles without factory installed fluorescent dye have a blue label.
IDENTIFICATION LABEL FOR VEHICLE
Vehicles with factory installed fluorescent dye have this identification
label on the front side of hood.
Wiring Diagrams and Trouble DiagnosisAJS00142
When you read wiring diagrams, refer to the following:

GI-15, "How to Read Wiring Diagrams" in GI section.

PG-4, "Wiring Diagram - POWER -" in PG section.
When you perform trouble diagnosis, refer to the following:

GI-11, "How to Follow Trouble Diagnoses" in GI section.

COMPONENT DESCRIPTION
Air Mix Door Motor
The air mix door motor is attached to the heater & cooling unit. It
rotates so that the air mix door is opened or closed to a position set
by the unified meter and A/C amp. Motor rotation is conveyed
through a shaft and the air mix door position is then fed back to the
unified meter and A/C amp. by PBR built-in air mix door motor.
DIAGNOSTIC PROCEDURE FOR AIR MIX DOOR

4. Position the center pulley puller on the end of the drive shaft,
and remove the pulley assembly using any commercially avail-
able pulley puller.
To prevent the pulley groove from being deformed, the puller
claws should be positioned into the edge of the pulley assembly.
5. Remove the field coil harness clip using a pair of pliers.
6. Remove the snap ring using external snap ring pliers.
Inspection
Clutch disc
If the contact surface shows signs of damage due to excessive heat,
replace clutch disc and pulley.
Pulley
Check the appearance of the pulley assembly. If the contact surface
of pulley sows signs of excessive grooving, replace clutch disc and
pulley. The contact surfaces of the pulley assembly should be
cleaned with a suitable solvent before reinstallation.
Coil
Check coil for loose connection or cracked insulation.
