TRUNK=NBBT0025S04Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid bumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINERNBBT0025S05Noises in the sunroof/headliner area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headliner and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATSNBBT0025S06When isolating seat noises it's important to note the position the seat is in and the load placed on the seat
when the noise is present. These conditions should be duplicated when verifying and isolating the cause of
the noise.
Cause of seat noise include:
1. Headrest rods and holders
2. A squeak between the seat pad cushion and frame
3. The rear seat back lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOODNBBT0025S07Some interior noises may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noises include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

If any gap or height difference between glass lid and roof is found,
check glass lid fit and adjust as follows:
Gap AdjustmentNBBT0018S03011. Open shade assembly.
2. Tilt glass lid up then remove side trim.
3. Loosen glass lid securing nuts (3 each on left and right sides),
then tilt glass lid down.
4. Adjust glass lid from outside of vehicle so it resembles ªA-Aº
as shown in the figure above.
5. Tilt glass lid up and down until it is adjusted to ªB-Bº as shown
in the figure above.
6. After adjusting glass lid, tilt glass lid up and tighten nuts.
7. Tilt glass lid up and down several times to check that it moves
smoothly.
Height Difference AdjustmentNBBT0018S03021. Tilt glass lid up and down.
2. Check height difference between roof panel and glass lid to
see if it is as ªA-Aº as shown in the figure above.
3. If necessary, adjust it by using one of following procedures.
IAdjust by adding or removing adjustment shim(s) between
glass lid and link assembly.
IIf glass lid protrudes above roof panel, add shim(s) or plain
washer(s) at sunroof mounting bracket or stud bolt locations to
adjust sunroof installation as required.
