LUBRICANT
LUBRICANT
Maintenance of Lubricant Quantity in CompressorINFOID:0000000001328166
The lubricant in the compressor circulates through the system with the refrigerant. Add lubricant to compres-
sor when replacing any component or after a large refriger ant leakage occurred. It is important to maintain the
specified amount.
If lubricant quantity is not maintained properly, the following malfunctions may result:
 Lack of lubricant: May lead to a seized compressor.
 Excessive lubricant: Inadequate cooling (thermal exchange interference)
LUBRICANT
LUBRICANT RETURN OPERATION
Adjust the lubricant quantity according to the test group shown below.
1.CHECK LUBRICANT RETURN OPERATION
Can lubricant return operation be performed?
 A/C system works properly.
 There is no evidence of a lar ge amount of lubricant leakage.
CAUTION:
If excessive lubricant leakage is noted, never perform the lubricant return operation.
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2.PERFORM LUBRICANT RETURN OPERATION, PROCEEDING AS FOLLOWS
1. Start the engine, and set to the following conditions:
- Engine speed: Idling to 1,200 rpm
- A/C switch: ON
- Blower speed: Max. position
- Temp. control: Optional [Set so that intake air temperature is 25 to 30 °C (77 to 86 °F).]
- Intake position: Recirculation (REC)
2. Perform lubricant return operation for about 10 minutes.
3. Stop the engine.
>> GO TO 3.
3.CHECK REPLACEMENT PART
Should the compressor be replaced?
YES >> Go to "LUBRICANT ADJUSTING PROCEDURE FOR COMPRESSOR REPLACEMENT".
NO >> Go to "LUBRICANT ADJUSTING PROCEDURE FOR COMPONENTS REPLACEMENT EXCEPT COMPRESSOR".
LUBRICANT ADJUSTING PROCEDURE FOR COMPONENTS REPLACEMENT EXCEPT COM-
PRESSOR
After replacing any of the followi ng major components, add the correct am ount of lubricant to the system.

COMPONENT DESCRIPTION
Brush-Less Motor
The blower motor utilizes a brush-less motor with a rotating magnet.
Quietness is improved over previous motors where the brush was
the point of contact and the coil rotated.
DIAGNOSIS PROCEDURE FOR BLOWER MOTOR
SYMPTOM: Blower motor operation is malfunctioning.
1.CHECK POWER SUPPLY FOR BLOWER MOTOR
1. Disconnect blower motor connector.
2. Turn ignition switch ON.
3. Check voltage between blower motor harness connector M78 terminal 1 and ground.
OK or NG
OK >> GO TO 2.
NG >> Check power supply circuit and 15A fuses [Nos. 10 and 11, located in the fuse block (J/B)]. Refer to PG-
77.
 If fuses are OK, check harness for open circuit. Repair or replace if necessary.
 If fuses are NG, check harness fo r short circuit and replace fuse.
2.CHECK BLOWER MOTOR GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Check continuity between blower motor harness connector M78 terminal 3 and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3.CHECK CIRCUIT CONTINUITY BETWEEN BLOWER MOTOR AND UNIFIED METER AND A/C AMP.
1. Disconnect unified meter and A/C amp. connector.

Removal and InstallationINFOID:0000000001328205
REMOVAL
1. Remove low-pressure pipe 2 and high-pressure pipe 3. Refer to ATC-133, "Removal and Installation of
Low-Pressure Pipe 2 and High-pressure Pipe 3".
CAUTION:
Cap or wrap the joint of evaporator, low-pressure pipe 1 and high-pressure pipe 2 with suitable
material such as vinyl tape to avoid the entry of air.
2. Slide evaporator to passenger side, and then remove intake sensor.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
 Replace O-rings of low-pressure pipe 1, 2 and high-p ressure pipe 2, 3 with new ones, and then apply
compressor oil to it when installing it.
 Mark the mounting position of intake sensor bracket prior to removal so that the reinstalled sensor
can be located in the same position.
 Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping
straight in axial direction.
 Insert piping securely until a click is heard.
 After piping connection is comp leted, pull male-side piping by hand to make sure that connection
does not come loose.
 When recharging refrigerant, check for leaks.
