3. Remove rear wiper arm. Refer to WW-74, "Removal and Installation".
4. Remove rear wiper motor. Refer to WW-76, "
Removal and Installation".
5. Remove back door window glass molding using a pliers. Refer to GW-16, "
Exploded View".
6. Apply protective tape around the back door window gl ass to protect the painted surface from damage.
7. Remove glass using piano wire or power cutting tool (A) and an inflatable pump bag (B).
NOTE:
Mark the body and the glass with matching ma rks if the back door window glass is reused.
WARNING:
Always wear safety glasses and heavy gloves to prevent injury.
CAUTION:
 Be careful not to scratch the glass when removing.
 Never set or stand the glass on its edge . Small chips may develop into cracks.
INSTALLATION
 The dam rubber should be installed in position.
 Use a genuine Nissan Urethane Adhesive Kit (if available) or an equivalent and follow the instructions pro-
vided with it.
 Open a door window while the urethane adhesive is curing. This prevents the glass from being forced out by
passenger compartment air pressure when all door windows are closed.
 Inform the customer that the v ehicle should remain stationary until the urethane adhesive has completely
cured (approximately 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. Never
let them come in contact with the skin and eyes.
 Use in an open, well ventilated location. Never br eathe the vapors. They may be harmful if inhaled.
Move immediately to an area with fresh air if affected by vapor inhalation.
 Driving the vehicle before the urethane adhesive has completely cured may affect the performance
of the rear window in case of an accident.
CAUTION:
 Perform adjustment of rear wipe r arm stop location. Refer to WW-74, "
Adjustment".
 Never use an adhesive which is past its usable term. Shelf life of this product is limited to six
months after the date of manufacture. Carefull y adhere to the expiration or manufacture date
printed on the box.
 Keep primers and adhesive in a cool, dry place. Id eally, they should be stored in a refrigerator.
 Never 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 com-
pletely cured. Curing time varies depending on temperature and humidity. The curing time
increases under lower temperature and lower humidity.
 If the substrate of the glass joining surface on th e back door panel side is exploded to the air,
exchange the back door assembly without recoating.
 Never apply paint on the back door panel surface wh ich is in contact with the glass when replacing
the back door assembly.
InspectionINFOID:0000000006220821
REPAIRING WATER LEAKAGE FOR BACK DOOR WINDOW GLASS
Leakage can be repaired without removing the glass.
Determine the extent of leakage if water is leaki ng between the urethane adhesive material and body or glass.
This can be done by applying water to the back door window glass area while pushing glass outward.

Component Description
Ambient sensor Ambient sensor measures ambient air temperature. The sensor uses a
thermistor which is sensitive to the change in temperature. The electrical
resistance of the thermistor decreases as temperature increases.
AV c o n t r o l u n i t AV control unit transmits front A/C control operation signal to A/C auto amp.
via CAN communication line.
A/C auto amp. A/C auto amp. controls front automatic air conditioning system by inputting
and calculating signals from each sensor and each switch. A/C auto amp.
has self-diagnosis function. Diagnosis of front automatic air conditioning
system can be performed quickly.
Blower unit Front blower motor Refer to

Combination meter Combination meter transmits vehicle speed signal to A/C auto amp. via
CAN communication line.
ECM ECM controls compressor according to status of engine and refrigerant.
ECM transmits engine coolant temperature signal to A/C auto amp. via
CAN communication line.
Engine coolant temperature sensor Engine coolant temperature sensor measures engine coolant temperature.
The sensor uses a thermistor which is sensitive to the change in tempera-
ture. The electrical resistance of the thermistor decreases as temperature
increases.
Front display Front display indicates operation status of front automatic air conditioning
system.
Front in-vehicle sensor Front in-vehicle sensor measures temperature of intake air that flows
through aspirator to passenger room. The sensor uses a thermistor which
is sensitive to the change in temperature. The electrical resistance of the
thermistor decreases as temperature increases.
