WATERLEAK REPAIR
Some waterleaks around the glass can be repaired with-
out removing the glass.
Important : This type of repair may be used only for ure-
thane– installed glass.
1. Remove the reveal molding in the area of the leak.
It may be necessary to remove the garnish molding
or the trim strip lace in order to locate the leak.
2. While spraying water over the leak area, carefully
push the glass outward in order to determine the
size of the leak.
3. Mark the location of the leak.
4. Use water to clean any dirt from the area. Dry the
area with an air hose.
5. Using a sharp knife, trim off the uneven edges of
the adhesive caulking material around the leak for a
distance of 75 to 100 mm (3 to 4 inches) on both
sides of the leak.
6. Using a sharp knife, trim off the uneven edges of
the adhesive material around the leak 75 to 100
mm (3 to 4 inches) on both sides of the leak.

DIAGNOSIS
WINDNOISE DIAGNOSIS
CAUTION : An assistant should drive the vehicle
while the technician checks for the location of the
windnoise, in order to prevent personal injury or ve-
hicle damage.
A test drive in the vehicle is necessary to accurately deter-
mine 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 follow-
ing items to aid in determining the location of the wind-
noise.
S A mechanics stethoscope or vacuum hose
S Masking tape
S Strip caulk
S A china marking pencil
S 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
interfere with the test.
3. Drive the vehicle at the speeds at which the noise
was noticed by the customer or until the noise is
produced. Do not exceed legal speed limits.
4. The windnoise is external if any of the following
conditions occur:
S The windnoise is caused by the wind.S The windnoise can be heard with the door glass
lowered and while the vehicle is being driven.
S 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.
S 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.
S Use a stethoscope or a vacuum hose to locate
the leak.
S Temporarily repair the leak with masking tape.
S Continue testing in order to determine if the
noise has been eliminated or if other leaks exist.
S When all leaks have been found, return to the
shop and make permanent repairs with the
proper alignment techniques and sealing materi-
als.

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 al-
ways indicate a faulty weatherstrip. A door or window ad-
justment may resolve the condition. Refer to Section 9P,
Doors or Section 9L, Glass and Mirrors.
