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.

DESCRIPTION AND OPERATION
DOOR LOCK STRIKER
The front and the rear door lock strikers each consist of
a striker with two screws threaded into a floating cage
plate in the B-pillars and C-pillars. The door is secured in
the closed position when the door lock fork snaps over
and engages the striker.
CHILDPROOF REAR DOOR LOCK
The childproof rear door locks help prevent passengers,
especially children, from opening the rear doors of the
vehicle from the inside.
In order to activate these locks, move the levers of both
rear doors to the lock position. Then, close both doors.
Rear passengers will be unable to open the doors from
the inside of the vehicle.
In order to deactivate the childproof rear door lock, un-
lock the door from the inside of the vehicle and open the
door from the outside. Move the lever to the unlock posi-
tion. The rear door will now work normally.
POWER DOOR LOCKS
The power door locks use a solenoid that is contained in
each door lock assembly. The door locks are activatedby the actuator on the inside door handle or by the lock
cylinder on the driver door only. When the driver door is
locked or unlocked by the actuator or lock cylinder, all
doors are locked or unlocked accordingly.
POWER WINDOWS
The power windows are controlled by electrical switches
on the front door tirm and operated by a motor at each
window regulator. The windows are lowered by pressing
the switch and raised by pulling up on the switch. The
window will stop movement when the switch is released
or when the window is completely open or closed.
TAILGATE STRUT
This vehicle is equipped with the gas struts. The struts
support the tailgate suitably when opening the tailgate.
The strut contained the high pressure compressed gas.
Therefore, be careful not to take apart, puncture, apply
heat or fire bacause the strut may explode.
