HOW TO LOCATE WIND NOISES
( 1) Attach cloth tape to every place which might conceivably be
the source of wind noise, such as panel seams, projections,moulding seams, glass and body seams, etc.
(2) Then make a road test in order to determine that the placesnot covered by tape are not sources of wind noise.
(3) Then remove the strips of tape one by one, making a road
test after each is removed, until a wind noise source is
discovered.
(4) When such a place is found, cover it again and continue with
the procedure so as to determine if there are any other noise
sources.
(5) If no others are found, the last remaining tape is the only
source.
(61 Cut the remaining piece of tape into smaller pieces, attach
it again as it was before, and then remove the pieces one
by one in the same way so as to narrow down the source.
(7) Check to confirm that wind noise occurs when the last
remaining tape is removed, and that noise does not occur
when it is re-attached.
(8) When the source(s) of the wind noise is finally located,
attach butyl tape, body sealer or similar material to obstructthis source as much as possible.

OPERATIONl With the ignition switch in the “ON” position,
rs;,press either the “UP” or “DOWN” side of the
power window (main or sub) switch. Electric
-*
current will then flow through sub fusible link No.5 to the power window motor and will operate
the power window motor to open or close the
power window glass.
lPress the DOWN side of the power window mainswitch located on the driver’s seat side all the
way. Then the switch will lock and the power
window motor will continue to operate until the
window glass is fully open.
NOTEFor detailed information on the operation of the
one-touch down (open) mechanism, refer to the
Technical Information Manual.l To disable both the main and sub switches
except the one located at the driver’s seat, placethe power window lock switch in the “LOCK
(ON)” position. With the switch in this position,
the power window motor will no longer operate
even if the switches are operated.
lThe power window motor has a circuit breaker to
prevent damage to the motor due to overcurrent.
Reference: Characteristics of Circuit BreakerAt normal temperatures
[ZO-25OC (68-77”F)I,bind the motor. Supply current, then the circuit
h
breaker will cut off the current in the first 4 to 40\&’seconds. The circuit breaker, if left alone, will
reset in less than 60 seconds.
TROUBLESHOOTING HINTS1. None of the door glasses can be opened or
closed.0 Check sub fusible link No. 5.0 Check the power window relays.
l Check the power window main switches.
2.Some, but not all, of the door glasses cannot be
opened or closed.
(I) Do not operate even if both the power
window main and sub switches are pressed.0 Check power window main switch.
l Check the power window motor which
does not operate.
(2) Do not operate only when either the main or
sub switch is pressed, but do operate when
both are pressed.0 Check power window switch which does
not operate.3. The one-touch switch function only does not
work.A0 Replace the power window main switch.

OPERATION
TROUBLESHOOTING HINTS
-.l If the inside lock knobs of the doors are placedin the LOCK (or UNLOCK) position, the switch inthe door lock actuator will be “OFF” (or “ON”),
and the output transistor will be “ON” for 0.5
second according to the timer function in the
door lock control unit (or theft-alarm control unit).As a result, the LOCK side (or UNLOCK side) of
the door lock relay will be “ON”, operating the
actuators of all of the doors.
NOTE
The door lock actuator contains a PTC thermistor
to prevent damage caused by overheating of the
motor. If the central door lock is frequently used,the actuator may temporarily fail to operate. If it
returns to normal in a few minutes, it is not
defective.

2.One of the door lock actuators fails to operate.
l Check the door actuator which fails to
operate.Cannot be placed in the LOCK or UNLOCK
position by the inside lock knob on either driver’s
or front passenger’s seat side.0 Check the switch in the actuator.0 Check the door lock control unit (or
theft-alarm control unit).
