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.

DAEWOO V–121 BL4
GENERAL DESCRIPTION
AND SYSTEM 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 the 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 ve-
hicle from the inside.
To activate the locks, move the levers of both rear doors
to the lock position. Then, close both doors. The rear pas-
sengers will be unable to open the doors from inside of the
vehicle.
To deactivate the locks, unlock the door from the inside of
the vehicle and open the door from the outside. Move the
lever to the unlock position. 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 activated by
the actuator on the inside door handle or by the lock cylin-
der on the driver’s side door only. When the driver’s side
door is locked or unlocked by the actuator or the lock cylin-
der, all doors are locked or unlocked accordingly.
POWER WINDOWS
The power windows are controlled by electrical switches
on the door panels and are operated by a motor at each
window regulator. Each door has a switch to control its
window, and the driver’s side door has four switches to
control all door windows on the vehicle. 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.
The driver’s side window opens automatically. By pressing
and releasing the switch, the driver ’s side window will low-
er and will stop only when the switch is activated again, or
when the window is completely open.
The driver’s side door control also contains a window lock
button that will prevent the operation of the front passen-
ger door or the rear door windows when pressed.
