1.

Trunk lid dumpers out of adjustment

2.

Trunk lid striker out of adjustment

3.

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/HEADLINING

Noises in the sunroof / headlining area can often be traced to one of the following items:

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 headlining 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.

SEATS

When isolating seat noise it is important to note the position the seat is in and the load placed on the seat
when the noise occurs. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Causes of seat noise include:
1.

Headrest rods and holder

2.

A squeak between the seat pad cushion and frame

3.

The rear seatback 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.

UNDERHOOD

Some interior noise may be caused by components under the hood or on the motor wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:

1.

Any component mounted to the motor wall

2.

Components that pass through the motor wall

3.

Motor 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, motor 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.
