REMOVAL
1. Remove front pillar garnish (LH and RH). Refer to INT-14, "Removal and Installation".
2. Remove partially headlining (front edge). Refer to INT-29, "
Removal and Installation".
3. Disconnect inside mirror harness connector.
4. Remove rain sensor cover and then disconnect rain sensor harness connector. Refer to WW-72,
"Removal and Installation".
5. Remove drip molding. Refer to EXT-43, "
Removal and Installation".
6. Remove windshield molding upper using pliers. Refer to GW-11, "
Exploded View".
7. Remove front wiper arm (LH and RH). Refer to WW-66, "
Removal and Installation".
8. Remove cowl top cover. Refer to EXT-21, "
Removal and Installation".
9. Remove front fender cover (LH and RH). Refer to EXT-21, "
Exploded View".
10. Disconnect wiper deicer harness connector (with wiper deicer).
11. Remove front pillar finisher (LH and RH). Refer to EXT-40, "
Removal and Installation".
12. Apply protective tape around the windshield glas s to protect the painted surface from damage.
13. 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 windshield glass is reused.
WARNING:
Always wear safety glasses and heavy gloves to prevent injury.
CAUTION:
 Never use a cutting knife or power cutting tool when the windshield glass is reused.
 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 sealant rubber and insulator 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 room air pressure when all door windows are closed.
 The molding must be installed securely so that it is in position and leaves no clearance.
 Inform the customer that the vehicle should rema in 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 ki t 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 windshield in case of an accident.
CAUTION:
 Perform adjustment of front wiper arms stop location. Refer to WW-66, "
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. Carefully 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 un attended 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 increases under
lower temperature and lower humidity.

REPAIRING WATER LEAKAGE FOR WINDSHIELD 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 windshield area while pushing glass outward.
Apply primer (if necessary) and then urethane adhes ive to the leakage point to stop the leakage.

< PRECAUTION >
PRECAUTIONS
 Turn the compressor shaft by hand more than five turns in both directions after compressor service
operation. This distributes equall y lubricant inside the compressor. Let the engine idle and operate
the compressor for one hour after the compressor is installed.
 Apply voltage to the new one and check for norma l operation after replacing the compressor magnet
clutch.
LEAK DETECTION DYE
CAUTION:
 The A/C system contains a fluorescent leak detect ion dye used for locating refrigerant leakages. An
ultraviolet (UV) lamp is required to il luminate the dye when inspecting for leakages.
 Wear always fluorescence enhancing UV safety goggles to protect eyes and enhance the visibility of
the fluorescent dye.
 The fluorescent dye leak detector is not a replacem ent for an electrical leak detector. The fluorescent
dye leak detector should be used in conjunction with an electrical leak detector to pin-point refriger-
ant leakages.
 Read and follow all manufacture’ s operating instructions and precau tions prior to performing the
work for the purpose of safet y and customer’s satisfaction.
 A compressor shaft seal should not necessarily be repaired because of dye seepage. The compres-
sor shaft seal should only be repaired after conf irming the leakage with an electrical leak detector.
 Remove always any remaining dye from the leakage area after repairs are completed to avoid a mis-
diagnosis during a future service.
 Never allow dye to come into contact with painted body panels or interior components. Clean imme-
diately with the approved dye cl eaner if dye is spilled. Fluorescent dye left on a surface for an
extended period of time cannot be removed.
 Never spray the fluorescent dye cleaning agent on hot surfaces (eng ine exhaust manifold, etc.).
 Never 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. Never use
HFC-134a (R-134a) leak detection dye in CFC-12 (R- 12) A/C system, or CFC-12 (R-12) leak detection
dye in HFC-134a (R-134a) A/C system, or A/C system damage may result.
 The fluorescent properties of the dye remains fo r three or more years unless a compressor malfunc-
tion occurs.
NOTE:
Identification
 Vehicles with factory installed fluorescent dye have a green label.
 Vehicles without factory installed fluorescent dye have a blue label.
