(VIN) is stamped in, or attached as a label to, the
following major parts of the engine and transaxle, as well as
main outer panels:
Engine cylinder block, Transaxle housing, Fender, Door, Quar-
ter panel, Hood, Liftgate, Bumpers
In addition, a theft-protection label is attached
to‘ replacement
parts for the body outer panel main components, and the same
data are stamped into replacement parts for the engine and the
transaxle.
Cautions regarding panel repairs
1. When repainting original parts, do so after first mask-
ing the theft-protection label, and, after painting, be
sure to peel off the masking tape.
2. The theft-protection label for replacement parts is
covered by masking tape, so such parts can be paintedas is. The masking tape should be removed after
painting is finished.
3.The theft-protection label should not be removed fromoriginal parts or replacement parts.

0When, with the ignition switch at the ON
position, a power-window (main or sub) switch
(“UP” side or “DOWN” side) is pressed, current
flows through sub-fusible link No. 8 and to the
power-window motor, thus causing the door
window glass to close or open.
When the “DOWN” side of the power-window
main switch at the driver’s side is pressed all the
way, it is locked at the pressed-in position, and
the power-window motor operates until the
door glass is fully opened.
When the power-window lock switch is set to
the “LOCK (ON)” position, the power-window
motor will not operate if any switch (main or sub)
other than at the driver’s side is operated.
A circuit breaker is provided in the power-window motor in order to prevent damage to the
motor as a result of excessive current.
For reference: Circuit breaker characteristics
Motor operation is restricted at high
temperatures
:
[20 - 25°C (68 - 77”F)].Current flow is cut by an initial current
occurs within 60 seconds if then left as
Iflow time of four to 40 seconds; resetis.The timer function of the ETACS permits the
power-window relay to remain ON for 30
seconds after the ignition switch is switched
OFF.If, during that period of time, the front door is
opened, the power-window relay is switched
OFF, and the power windows can no longer be
operated.
TROUBLESHOOTING HINTS1. All door windows cannot be opened or closed.
l Check sub-fusible link No. 8.
l Check the power-window relay.
l Check the power-window main switch.
2.One of the door windows cannot be opened or
closed.
(1) Neither of the power-window switches
(main or sub) operates.
l Check the power-window main switch.
lCheck the power-window motor for the
power window that does not operate.
(2) Either the power-window main switch or
sub switch does not operate.
lCheck the power-window switch for the
power window that does not operate.
3. The one-touch down switch function only does
not operate.
lReplace the power-window main switch.
4.The power window operation by ETACS control
after the ignition switch is switched OFF does
not function.
l Refer to
P.42-43.
