Inspection INFOID:0000000004307411
WIND DEFLECTOR
Check that the wind deflector (1) moves freely within the sunroof unit
assembly while manually pressing down and releasing. If a malfunc-
tion is detected, remove and visually check the deflector for damage,
deteriorated components, or foreign objects within mechanism.
Check to determine if a sufficient amount of grease has been applied
to the pivot areas for non-binding operation, if not add grease as
required. If it is damaged, replace it with a new one. If no damage is
found, reinstall it properly.
⇐ : Vehicle front
LINK ASSEMBLY AND WIRE
NOTE:
Before replacing a suspect part, make sure it is the source of noise being experienced.
1. Check link to determine if coated film has peeled off to such an extent that substrate is visible. Check also
to determine if link is the source of noise. If it is, replace it.
2. Visually check to determine if a sufficient amount of grease has been applied to wire or rail groove of the
sunroof unit assembly. If not, add grease as required.
3. Check wire for any damage or deterioration. If any damage is found, replace sunroof unit assembly.
WEATHERSTRIP
1. Visually check weatherstrip for dam age, deterioration, or deformation.
• Open glass lid assembly enough to inspect front edge of weatherstrip.
• Tilt up glass lid assembly fully to in spect sides and rear edge of weatherstrip.
If any area of the weatherstrip is found to be damaged, replace the glass lid assembly. Refer to RF-22," Removal and Installation " .
2. Check for leakage around glass lid. • Close glass lid fully.
• Pour water around surface to determine area of concern.
- For gaps or misalignment, adjust glass lid to specifications. Refer to RF-27, " Fitting Adjustment " .
- For damaged sealing surfaces, either replace glass lid RF-22, " Removal and Installation " , or repair the
panel BL-307, " Precaution in Repairing High Strength Steel " .

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Work Flow INFOID:0000000004306504
CUSTOMER INTERVIEW Interview the customer if possible, to determine the c onditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interv iew to document the facts and conditions when the noise occurs and any
customer's comments; refer to SE-9, " Diagnostic Worksheet " . This information is necessary to duplicate the
conditions that exist when the noise occurs.
• The customer may not be able to provide a detailed descr iption or the location of the noise. Attempt to obtain
all the facts and conditions that exist when the noise occurs (or does not occur).
• If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer is
concerned about. This can be accomplished by test driving the vehicle with the customer.
• After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
• Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces
= higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.
• Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow mo vement/twisting with a rotational movement/pitch depen-
dent on materials/often brought on by activity.
• Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contac t/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
• Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/someti mes repeating/often brought on by driver action.
• Tick—(Like a clock second hand) Tick characteristics include gentle contacting of li ght materials/loose components/can be caused by driver
action or road conditions.
• Thump—(Heavy, muffled knock noise) Thump characteristics include softer k nock/dead sound often brought on by activity.
• Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
• Often the degree of acceptable noise level will vary depending upon the person. A noise that you may judge as acceptable may be very irritating to the customer.
• Weather conditions, especially humidity and temperature, may have a great effect on noise level.
DUPLICATE THE NOISE AND TEST DRIVE 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. SBT842

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 urethane
tape. A NISSAN Squeak and Rattle Kit (J-43980) is av ailable through your authorized NISSAN Parts Depart-
ment.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
Always check with the Parts Department for the latest parts information.

REMOVAL WARNING:
When servicing the SRS, do not work from directly in front of air bag module.
CAUTION:
• Before servicing the SRS, turn ignition switch OFF, disconnect both battery terminals and wait at
least three minutes.
• Do not tap or bump the steering wheel.
• Do not disassemble the spiral cable.
• Do not allow oil, grease or water to co me in contact with the spiral cable.
• Replace the spiral cable if it has b een dropped or sustained an impact.
• With the steering linkage disconn ected, the spiral cable may snap by turning the steering wheel
beyond the limited number of turns. The spiral cable can be turned counterclockwise about 2.5 turns
from the neutral position.
1. Disconnect the negative and positive battery term inals, then wait at least three minutes.
2. Set the front wheels to the straight-ahead/neutral position.
3. Remove the steering wheel. Refer to PS-6 .
4. Remove the column cover upper and lower.
5. Disconnect wiper and washer switch connector (1). Then while pressing tabs (2), pull wiper and washer switch away from spiral
cable to remove. 2. Steering wheel 3. Lighting and turn signal switch

6. Disconnect lighting and turn signal switch connector (1). Then while pressing tabs (2), pull lighting and turn signal switch
toward driver door to remove.
7. Remove the screws, then release the tab at the top and pull the spiral cable away from the steering column assembly.
8. Disconnect spiral cable connectors.
INSTALLATION
Installation is in the reverse order of removal.
• Align spiral cable correctly when installing steering wheel. Make sure spiral cable alignment and centering marks (B) are matched
and in the neutral position. The neutra l position is detected by turn-
ing left 2.5 revolutions from the right end position, ending with the
locating pin (A) at the top. Place steering wheel in straight ahead
position, then install it with the locating pin hole (C) directly over
spiral cable locating pin.
• After the work is completed, perform self-diagnosis to make sure
no malfunction is detected. Refer to SRS-19, " SRS Operation
Check " . WHIA0316E
