REMOVAL
1. Remove inside mirror. Refer to MIR-10, "Removal and Installation".
2. Partially remove the headlining (front edge). Refer to INT-17, "
Removal and Installation".
3. Remove cowl top cover. Refer to EXT-18, "
Removal and Installation".
4. Apply a protective tape around the windshield gl ass to protect the painted surface from damage.
• Remove glass using piano wire or power cutting tool and an inflatable pump bag.
• If the windshield glass is to be reused, mark the body and the glass with mating marks.
WARNING:
When cutting the glass from the vehicle, always wear safety glasses and heavy gloves to help prevent
glass splinters from entering your eyes or cutting your hands.
CAUTION:
• When the windshield glass is to be reused, do not use a cutting knife or power cutting tool.
• Be careful not to scratch the glass when removing.
• Do not set or stand glass on its ed ge. Small chips may develop into cracks.
INSTALLATION
Installation is in the reverse order of removal.
• Use a genuine NISSAN Urethane Adhesive Kit (if availabl e) or equivalent and follow the instructions fur-
nished with it.
• 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 so that it is in position and leaves 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.

FRONT DOOR GLASS AND REGULATOR
NOTE:
If any of the following work has been done, reset the power window motor limit switch.
• Removal and installation of the regulator assembly.
• Removal and installation of the power window motor from the regulator.
• Installation of a new glass window.
• Installation of a new glass run.
Check the label on the power window motor for the part number. If the power window motor part number
matches one of the following, the motor must be removed from the regulator and the limit switch reset using
the "INSTALLATION WITHOUT RESET SWITCH" pr ocedure in "FRONT DOOR GLASS REGULATOR
ASSEMBLY".
• 80730-ZT01A
• 80731-ZT01A
• 80730-ZM70B
• 80731-ZM70B
If the power window motor part number does not match one of the part numbers above, the limit switch can be
reset in the vehicle using the "INSTA LLATION WITH RESET SWITCH" procedure.
NOTE:
• The label can be checked with the power window motor in the vehicle by using a mirror.
• Some of the power window motors with the part num bers above may appear to have a reset switch, but it will
not reset the limit switch.
Fitting Inspection
• Check that the glass is securely fit into the glass run groove.
• Lower the glass slightly [approximately 10 to 20 mm (0 .39 to 0.79 in)] and check that the clearance to the
sash is parallel. If the clearance between the glass and sash is not parallel, loosen the regulator bolts, guide
rail bolts, and glass and guide rail bolts to correct the glass position.
FRONT DOOR GLASS REGULATOR ASSEMBLY
Removal
1. Remove the front door finisher panel. Refer to INT-11, "Removal and Installation".
2. Position aside the vapor barrier.
3. Remove the hole cover over rear glass bolt.
4. Operate the power window main switch to raise/ lower the door window until the glass bolts can be seen.
5. Remove the inside seal.
6. Remove the glass bolts.
7. Raise the front door glass and hold it in place with suitable tool.
8. Disconnect the harness connector fr om the regulator assembly.
9. Remove the bolts and the regulator assembly.
Disassembly And Assembly
Remove the regulator motor from the regulator assembly.
Inspection After Removal
Check the regulator assembly for the following items. If a malfunc-
tion is detected, replace or grease it.
• Wire wear
• Regulator deformation
• Grease condition for each sliding part The arrows in the figure show the application points of the body
grease.
Installation
If any of the following work has been done, reset the power window motor limit switch.
• Removal and installation of the regulator assembly.

FLUORESCENT LEAK DETECTOR
FLUORESCENT LEAK DETECTOR
Checking of Refrigerant LeaksINFOID:0000000001516646
PRELIMINARY CHECK
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C oil leak-
age, damage, and corrosion. Any A/C oil leakage may indicate an area of refrigerant leakage. Allow extra
inspection time in these areas when using either an el ectronic refrigerant leak detector (J-41995) or fluores-
cent dye leak detector (J-42220).
If any dye is observed using a fluorescent dye leak detector (J-42220), confirm the leak using a electronic
refrigerant leak detector (J-41995). It is possible that the dye is from a prior leak that was repaired and not
properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic refrigerant leak detector (J-41995), move the probe
along the suspected leak area at 25 - 50 mm (1 - 2 in) per second and no further than 6 mm (1/4 in) from the
component.
CAUTION:
Moving the electronic refrigerant l eak detector probe slower and closer to the suspected leak area will
improve the chances of finding a leak.
Checking System for L eaks Using the Fluorescent Dye Leak DetectorINFOID:0000000001516647
1. Check the A/C system for leaks using the fluorescent dye leak detector and safety goggles (J-42220) in a
low sunlight area (area without windows preferable). Il luminate all components, fittings and lines. The dye
will appear as a bright green/yellow area at the point of leakage. Fluorescent dye observed at the evapo-
rator drain opening indicates an evaporator core asse mbly leak (tubes, core or expansion valve).
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or cloth, then inspect the shop rag or cloth with the fl uorescent dye leak detector (J-42220) for dye residue.
3. After the leak is repaired, remove any residual dye using refrigerant dye cleaner (J-43872) to prevent
future misdiagnosis.
4. Perform a system performance check and then verify t he leak repair using a electronic refrigerant leak
detector (J-41995).
NOTE:
• Other gases in the work area or substances on the A/C components, for example, anti-freeze, wind-
shield washer fluid, solvents and oils, may falsely tri gger the leak detector. Make sure the surfaces to be
checked are clean.
• Clean with a dry cloth or blow off with shop air.
• Do not allow the sensor tip of the electronic refri gerant leak detector (J-41995) to contact with any sub-
stance. This can also cause false readings and may damage the detector.
Dye InjectionINFOID:0000000001516648
NOTE:
This procedure is only necessary when recharging the system or when the compressor has seized and must
be replaced.
1. Check the A/C system static (at rest) pressure . Pressure must be at least 345 kPa (3.52 kg/cm
2 , 50 psi).
2. Pour one bottle 7.4 cc (1/4 ounce) of the HFC-134a (R -134a) fluorescent leak detection dye (J-41447) into
the HFC-134a (R-134a) dye injector (J-41459).
CAUTION:
If repairing the A/C system or replacing a co mponent, pour the HFC-134a (R-134a) fluorescent leak
detection dye (J-41447) directly into the open system connection and proceed with the service
procedures.
3. Connect the refrigerant dye injector (J-41459) to the low-pressure service valve.
4. Start the engine and switch the A/C system ON.
5. When the A/C system is operating (compressor running), inject one bottle 7.4 cc (1/4 ounce) of HFC-134a (R-134a) fluorescent leak detection dye (J-41447) through the low-pressure service valve using HFC-
134a (R-134a) dye injector (J-41459). Refer to the manufacturer's operating instructions.
