< SYMPTOM DIAGNOSIS >
SQUEAK AND RATTLE TROUBLE DIAGNOSES
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or lo cation of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli-
cate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load (electrical load, half-cl utch on M/T models, drive position on A/T models).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
 Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
 If it is difficult to duplicate the noise, drive the v ehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, chec k ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follo w the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1. Narrow down the noise to a general area. To help pi npoint the source of the noise, use a listening tool
(Chassis Ear: J-39570, Engine Ear and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:
 Removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fastener can be broken
or lost during the repair, resulting in the creation of new noise.
 Tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only tem-
porarily.
 Feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the
noise.
 Placing a piece of paper between components that you suspect are causing the noise.
 Looking for loose components and contact marks. Refer to GW-7, "
Inspection Procedure".
REPAIR THE CAUSE
 If the cause is a loose component, tighten the component securely.
 If the cause is insufficient clearance between components:
- Separate components by repositioning or loos ening and retightening the component, if possible.
- Insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or ure-
thane tape. A Nissan Squeak and Rattle Kit (J-43980) is available through your authorized Nissan Parts
Department.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
NOTE:
Always check with the Parts Departm ent for the latest parts information.
The following materials are contained in the Nissan Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.

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".

< 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.
