DIAGNOSTIC INFORMATION AND PROCEDURES
WINDNOISE DIAGNOSIS
Caution: An assistant should drive the vehicle while
the technician checks for the location of the wind-
noise, in order to prevent personal injury or vehicle
damage.
A test drive in the vehicle is necessary to accurately de-
termine the location of the windnoise. Often there is a
primary leak and secondary leaks. Failure to repair all
leaks will only reduce the windnoise, not eliminate it.
During the test drive the technician should bring the fol-
lowing items to aid in determining the location of the
windnoise.

A mechanics stethoscope or vacuum hose

Masking tape

Strip caulk

A china marking pencil

A screwdriver
Perform the following steps in order to conduct the road
test:
1. Choose a route that includes smooth straight streets
that run in all four directions (north, south, east, and
west).
2. Choose streets with little traffic or noise that would in-
terfere with the test.
3. Drive the vehicle at the speeds at which the noise
was noticed by the customer or until the noise is pro-
duced. Do not exceed legal speed limits.
4. The windnoise is external if any of the following condi-
tions occur:

The windnoise is caused by the wind.

The windnoise can be heard with the door glass
lowered and while the vehicle is being driven.

The windnoise is eliminated when tape is placed
over various moldings and gaps.5. Internal windnoise is air leaving the vehicle and
should be repaired in the following manner.

In order to locate the leak, tape off the body lock
pillar pressure relief valves. This will cause air
pressure to build up inside the vehicle and en-
hance the windnoise.

Use a stethoscope or a vacuum hose to locate the
leak.

Temporarily repair the leak with masking tape.
D109A307

Continue testing in order to determine if the noise
has been eliminated or if other leaks exist.

When all leaks have been found, return to the shop
and make permanent repairs with the proper align-
ment techniques and sealing materials.

WINDNOISE REPAIR
Windnoise leak repairs are very similar to waterleak re-
pairs. Refer to Section 9I, Waterleaks. The actual proce-
dure depends on the type of seal being repaired. Leaks
around the door opening weatherstrips do not always in-
dicate a faulty weatherstrip. A door or window adjust-
ment may resolve the condition. Refer to Section 9L,
Glass and Mirrors.

SQUEAK AND RATTLE REPAIR
Squeaks and rattles are caused by the unwanted move-
ment between parts of a vehicle. There are three means
to prevent squeaks or rattles.

Attach the parts securely so that there is no rela-
tive motion during the operation of the vehicle.

Separate the parts so that there is no contact dur-
ing operation.

Insulate the parts so that no squeaks or rattles oc-
cur with the movement of the parts. Low uniform
friction surfaces can be used to eliminate “stick–
slip” motion.

tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in B unless otherwise
noted.

shield glass, the back glass, and the inside rearview
mirror.
INSIDE REARVIEW MIRROR
The inside rearview mirror can be manually adjusted up/
down, fore/aft, and left/right. The rearview mirror pivots
in two places: the ball-and-socket mirror pivot and the
up/down hinge lever at the mirror support.
OUTSIDE REARVIEW MIRRORS
Three types of outside rearview mirrors are available.
The outside rearview mirrors are adjusted by hand
which is standard. The remote control and the electric
outside rearview mirrors are optional. The outside rear-
view mirrors are installed on the front doors.

DIAGNOSTIC INFORMATION AND PROCEDURES
TESTING REAR WINDOW DEFOGGER GRID LINE
D109E301
If it has been observed during use that a grid line is inop-
erative, the following procedure can be used to find the
break. If none of the grid lines is operating, a full system
diagnosis should be completed before attempting to re-
pair the grid lines.
1. Turn the ignition ON.
2. Turn on the rear window defogger.
Notice: Use care when touching the voltmeter terminals
to a grid line. If the terminals are roughly applied, the grid
line may be scratched, resulting in an open circuit.
3. From the inside of the vehicle, connect a voltmeter to
each end of a grid line. The voltmeter will indicate bat-
tery voltage if the grid line is open.
4. If a grid line is found to be open, move a voltmeter ter-
minal from one side of the grid line and retest at apoint nearer to the other side of the window. Continue
to retest, each time bringing one of the voltmeter ter-
minals closer to the opposite side of the window from
where it was originally connected. The break in the
grid line is at the point where the voltmeter begins
reading 0 volts instead of battery voltage.
5. Use a marking crayon to lightly mark the break point
on the rear window. Mark the glass instead of mark-
ing directly on the grid line, and make the mark far
enough from the grid line so that the mark can easily
be removed without disturbing the repair.
6. Use a grid line repair kit to fix the break in the grid line.
Refer to “Rear Window Defogger Grid Line Repair” in
this section.
