< REMOVAL AND INSTALLATION >
REAR WINDOW GLASS
4. Remove windshield glass using piano wire or power cutting tool (A) and an inflatable pump bag (B).
• Apply protective tape around the rear window gla ss to protect the painted surface from damage.
• If the rear window glass is to be reused, mark the body and the glass with matching marks.
WARNING:
When cutting the glass from the vehicle, always wear safety glasses and heavy gloves to help pre-
vent glass splinters from entering your eyes or cutting your hands.
CAUTION:
• Be careful not to scratch the glass when removing.
• Do not set or stand the glass on its ed ge. Small chips may develop into cracks.
• Apply protective tape around th e rear window glass to protect the painted surface from damage.
INSTALLATION
Installation is in the reverse order of removal.
• If repainting near the rear window flange area, protect the flange adhesion area by masking the flange.
• Use a Genuine NISSAN Urethane Adhesive Kit (if availabl e) or equivalent and follow the instructions fur-
nished with it.
• Adhesive shall be continuously applied to ensure watert ightness. Glass installation shall be finished within
five minutes after applying the adhesive.
• The start and finish of the urethane adhesive application should be located at the bottom to assure water-
tightness.
• While the urethane adhesive is curing, open a door window . This will prevent the glass from being forced out
by passenger compartment air pressure when a door is closed.
• The molding must be installed securely to the rear window glass to avoid looseness and will leave no gap.
• Inform the customer that the vehicle should rema in stationary until the urethane adhesive has completely
cured (preferably 24 hours). Curing time varies with temperature and humidity.
WARNING:
• Keep heat and open flames away as primers and adhesive are flammable.
• The materials contained in the kit are harmful if swallowed, and may irritate skin and eyes. Avoid
contact with the skin and eyes.
• Use in an open, well ventilated location. Avoid br eathing the vapors. They can be harmful if inhaled.
If affected by vapor inhalation, imme diately move to an area with fresh air.
• Driving the vehicle before the urethane adhesive has completely cured may affect the performance
of the rear window in case of an accident.
CAUTION:
• Do not use an adhesive which is past its usable te rm. Shelf life of this product is limited to six
months after the date of manufacture. Carefully a dhere to the expiration or manufacture date printed
on the box or product.
• Keep primers and adhesive in a c ool, dry place. Ideally, they should be stored in a refrigerator.
• Do not leave primers or adhesive cartridge unattended with their caps open or off.
• The vehicle should not be driven for at least 24 hours or until the urethane adhesive has completely
cured. Curing time varies depe nding on temperature and humidity . The curing time will increase
under lower temperature and lower humidity.
REPAIRING WATER LEAKS FOR REAR WINDOW GLASS
• Leaks can be repaired without removing and reinstalling glass.
• If water is leaking between the urethane adhesive material and body or glass, determine the extent of leak-
age.
• This can be done by applying water to the side window area while pushing glass outward.
• To stop the leak, apply primer (if necessary) and then urethane adhesive to the leak point.

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.

2. The blower speed dial is turned completely counterclockwise to the OFF position.
3. The A/C switch is manually turned OFF.
In other words, the compressor ON request cannot be turned off in D/F or DEF modes.
REFRIGERANT PRESSURE PROTECTION
The refrigerant system is protected against excessively high- or low-pressures by the refrigerant pressure sen-
sor, located on the liquid tank on the condenser. The refr igerant pressure sensor detects the pressure inside
the refrigerant line and sends a voltage signal to the EC M. If the system pressure rises above or falls below
the following values, the ECM requests the IPDM E/ R to de-energize the A/C relay and disengage the com-
pressor.
• 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
PRESSURE RELIEF VALVE
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.
When the pressure of refrigerant in the system incr eases to an abnormal level [more than 2,990 kPa (30.5 kg/
cm
2, 433.6 psi)], the release port on the pressure relief valve automatically opens and releases refrigerant into
the atmosphere.
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.
OPERATING RATE CONTROL
When the set temperature is other than fully cold or the air outlet is “VENT”, “B/L” or “FOOT”, the front air con-
trol controls the compressor activation depending on ambient temperature.
Door ControlINFOID:0000000009463200
DOOR MOTOR CONTROL
• A Local Control Unit (LCU) is built into each door motor and detects the door position by using a Position
Balanced Resistor (PBR).
• Each door motor LCU has a unique address. The front air control communicates with the door motor LCUs by using each door’s unique communication address. The front air control sends requested door position
commands to each door motor LCU via a Local Interconnect Network (LIN) communication line. Each door
motor’s LCU receives the command and sends back a door position feedback signal.
• Each LCU controls each door to the appropriate posit ion depending on the control signal from the front air
control. When the door movement is complete, the LCU transmits a signal to the front air control indicating
that the door movement is complete.
