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 look directly into UV lamp light source.
NOTE:
 For continuous operating time of UV lamp, fo llow the manufacturer operating instructions.
 Illuminate piping joints from different angles us ing UV lamp and check that there is no leakage.
 Use a mirror in area that is difficult to see to check refrigerant leakage.
 Refrigerant leakage from evaporator can be detected by soaking cotton swab or a similar material with
drain hose water and illuminating it using UV lamp.
 Dust, dirt, and packing materials adhesive used for condenser, evaporator, and other locations may flu- oresce. Be careful not to misidentify leakage.
5. Repair or replace parts where refrigerant leak age occurs and wipe off fluorescent leak detection dye.
NOTE:
Completely wipe off fluorescent leak detection dy e from gaps between parts, screw threads, and others
using a cotton swab or similar materials.
6. Use a UV lamp to check that no fluorescent leak detection dye remains after finishing work. WARNING:
Never look directly into UV lamp light source.
NOTE:
 For continuous operating time of UV lamp, fo llow the manufacturer operating instructions.
 Dust, dirt, and packing materials adhesive used for condenser, evaporator, and other locations may flu-
oresce. Be careful not to misidentify leakage.
CHECK REFRIGERANT LEAKAGE USIN G ELECTRICAL LEAK DETECTOR
WARNING:
Never check refrigerant leakage while the engine is running.
CAUTION:
Be careful of the following items so that in accurate checks or misidentifications are avoided.
 Never allow refrigerant vapor, shop chemical vapors, cigarette smoke, or others around the vehicle.
 Always check refrigerant leakage in a low air flow environment so that refrigerant may not disperse
when leakage occurs.
1. Stop the engine.
2. Connect recovery/recycling/recharging equipment or manifold gauge set to A/C service valve.
3. Check that A/C refrigerant pressure is 345 kPa (3.52 kg/cm
2, 50 psi) or more when temperature is 16 °C
(61 °F) or more. When pressure is lower than the spec ified value, recycle refrigerant completely and fill
refrigerant to the specified level.
NOTE:
Leakages may not be detected if A/C refri gerant pressure is 345 kPa (3.52 kg/cm
2, 50 psi) or less when
temperature is less than 16 °C (61 °F).
4. Clean area where refrigerant leakage check is per formed, and check refrigerant leakage along all sur-
faces of pipe connections and A/C system com ponents using electrical leak detector probe.
CAUTION:
 Continue checking when a leakage is found. Always continue and complete checking along all
pipe connections and A/C system co mponents for additional leakage.
 When a leakage is detected, clean leakage area using compressed air and check again.
 When checking leakage of cooling unit inside, al ways clean inside of drain hose so that the
probe surface may not be exposed to water or dirt.
NOTE:
 Always check leakage starting from high-pressure side and continue to low-pressure side.
 When checking leakage of cooling unit inside, operate blower fan motor for 15 minutes or more at the maximum fan speed while the engine is stopped, and then insert electrical leak detector probe into drain
hose and hold for 10 minutes or more.
 When disconnecting shut-off valve that is connected to A/C service valve, always evacuate remaining
refrigerant so that misidentification can be avoided.
5. Repair or replace parts where refrigerant leak age is detected. (Leakage is detected but leakage area is
unknown. GO TO 6.)
6. Start the engine and set A/C control in the following conditions.  A/C switch ON
 Air flow: VENT (ventilation)
 Intake door position: Recirculation
