MAINTENANCE OF OIL LEVEL
The compressor oil is circulating in the system together wi th the refrigerant. It is necessary to fill compressor
with oil when replacing A/C system parts or when a large amount of refrigerant leakage is detected. It is impor-
tant to always maintain oil level within the spec ified level, otherwise the following conditions may occur:
• Insufficient oil amount: Stuck compressor
• Excessive oil amount: Insufficient coo ling (caused by insufficient heat exchange)
InspectionINFOID:0000000009463931
If a compressor is malfunctioning (internal noise, insufficient cooling), check the compressor oil.
1.COMPRESSOR OIL JUDGMENT
1. Remove the compressor. Refer to HA-30, "COMPRESSOR : Removal and Installation"
.
2. Sample compressor oil and judge below according to the figure.
Judgement result 1>>Replace compressor only.
Judgement result 2>>Replace compressor and liquid tank.
Perform Oil Return OperationINFOID:0000000009463932
CAUTION:
If a large amount of refrigerant or oil leakage is detected, do not perform oil return operation.
1. Start the engine and set to the following conditions: • Engine speed: Idling to 1,200 rpm
• A/C switch: ON
• Fan (blower) speed: Maximum speed set
• Intake door position: Recirculation
• Temperature setting: Full cold
2. Perform oil return operation for approximately 10 minutes.
3. Stop the engine.
4. Oil return operation is complete.
Oil Adjusting Procedure for Component s Replacement Except Compressor

SYSTEM
Air Outlet Control
INFOID:0000000009463097
• While air outlet is in automatic control, A/C auto amp. selects the mode door position depending on a target air mix door angle and
outlet air temperature calculated from sunload.
• If ambient temperature is excessively low, D/F is selected to pre- vent windshield fogging when air outlet is set to FOOT.
Compressor ControlINFOID:0000000009463098
DESCRIPTION
• When the compressor activation condition is satisfied whil e blower motor is activated, A/C auto amp. trans-
mits A/C ON signal and blower fan ON signal to ECM via CAN communication.
• ECM judges that the compressor can be activated depending on the state of each sensor (refrigerant pres-
sure sensor signal and others) and transmits A/C comp ressor request signal to IPDM E/R via CAN commu-
nication.
• IPDM E/R turns A/C relay ON and activate s the compressor depending on request from ECM.
COMPRESSOR PROTECTION CONTROL AT PRESSURE MALFUNCTION
When high-pressure side value that is detected by refrigerant pressure sensor is as per the following state,
ECM requests IPDM E/R to turn A/C relay OFF and stops the compressor.
• 3.12 MPa (31.82 kg/cm
2, 452.4 psi) or more (When the engine speed is less than 1,500 rpm)
• 2.74 MPa (27.95 kg/cm
2, 397.3 psi) or more (When the engine speed is 1,500 rpm or more)
• 0.14 MPa (1.43 kg/cm
2, 20.3 psi) or less
COMPRESSOR OIL CIRCULATION CONTROL
When the engine starts while the engine coolant temperature is 56 °C (133 °F) or less, ECM activates the com-
pressor for approximately 6 seconds and circulates the compressor lubricant once.
LOW TEMPERATURE PROTECTION CONTROL
• When intake sensor detects that front evaporator fin temperature is 2.5 °C (37 °F) or less, A/C auto amp. requests ECM to turn com-
pressor OFF, and stops the compressor.
• When the front evaporator fin temperature returns to 5.0 °C (41 °F)
or more, the compressor is activated.
OPERATING RATE CONTROL
When set temperature is other than fully cold or air out let is “VENT”, “B/L” or “FOOT” A/C auto amp. controls
the compressor activation depending on ambient temperature.
AIR CONDITIONING CUT CONTROL
When set engine is running is excessively high load conditi on, ECM requests IPDM E/R to turn A/C relay OFF,
and stops the compressor. Refer to EC-56, "AIR CONDITIONING CUT CONT ROL : System Description (with
automatic air conditioner)" (QR25DE) or EC-573, "AIR CONDITIONING CUT CONTROL : System Descrip-
tion" (VQ35DE) for details.

INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. Cluster lid A and the instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar finisher
4. Instrument panel to windshield
5. Instrument panel pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noi se. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicone spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
CAUTION:
Do not use silicone spray to isolate a squeak or ra ttle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shift selector assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation pr ocedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them wh ile driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the ar eas with felt cloth tape or insulator foam blocks from
the NISSAN Squeak and Rattle Kit (J-50397) to repair the noise.
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid bumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, se curing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sun visor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
OVERHEAD CONSOLE (FRONT AND REAR)
Overhead console noises are often caused by the cons ole panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the c onsole at the clip locations until the clips engage.
