         Toyota Power Windows

         Celica

    DESCRIPTION & OPERATION
         System components consist of a power window relay, power
window switches and power window motors for each door. With ignition
switch in ON position, battery voltage is supplied through power
window relay to power window switches. Power window switch supplies
power and ground for power window motors.
         Driver's side power window switch offers one-touch operation
of driver's side window. Driver's side power window switch also
includes a lock-out feature to prevent passengers from operating any
of the other power window switches.

    TROUBLE SHOOTING

    ALL WINDOWS INOPERATIVE & LOCK-OUT IS INOPERATIVE
         Check for defective fuse (ALT, AM1, DOOR, GAUGE, POWER),
ignition switch, door lock control relay, driver's side power window
switch and wiring circuits.

    ALL WINDOWS INOPERATIVE & LOCK-OUT OPERATES NORMAL
         Check for defective fuse (GAUGE, POWER), ignition switch,
door lock control relay, driver's side power window switch or power
main relay.

    LOCK SWITCH INOPERATIVE
        Check driver's side power window lock switch.

    WINDOW LOCK ILLUMINATION DOES NOT OPERATE
        Check driver's side power window switch.

    ONE-TOUCH FEATURE IS INOPERATIVE
        Check driver's side power window switch.

    ONE WINDOW DOES NOT OPERATE
         Check driver's side power window switch for appropriate
window, power window switch, power window motor and wiring circuits
for appropriate window.

NOTE:   For door lock control relay testing, see DOOR LOCKS - POWER
        article in the ACCESSORIES/SAFETY EQUIPMENT section. For
        ignition switch testing, see STEERING COLUMN SWITCHES article
        in the ACCESSORIES/SAFETY EQUIPMENT section.

    TESTING
        POWER WINDOW SWITCH ILLUMINATION TEST (DRIVER'S SIDE SWITCH)
NOTE:            Illumination test is for all switches at driver's side power
                 window switch.

         1) Using a 12 volt battery, connect jumper wire from positive
battery terminal to driver's side power window switch connector
terminal No. 6. See Fig. 1. Connect jumper wire from negative battery
terminal to connector terminal No. 3. Ensure power window switches
illuminate.
         2) Put power window lock switch in lock position. Ensure
passenger side power window switch does not illuminate. If
illumination is not as described, replace driver's side power window
switch.

        POWER WINDOW SYSTEM CURRENT TEST
         1) Disconnect connector from driver's side power window
switch. Connect positive lead of ammeter to driver's side power window
switch connector (harness side) terminal No. 5.
         2) Connect ammeter negative lead to negative terminal of 12
volt battery. Connect jumper wire from positive battery terminal to
driver's side power window switch connector terminal No. 1. See
Fig. 1.
         3) While lowering driver's side window, current should be
about 7 amperes. When window operation is stopped, current should
increase to about 14.5 amperes or more. If current is as described,
replace driver's side power window switch. If current is not as
described, check and repair appropriate circuit.

        POWER WINDOW SWITCH CONTINUITY TEST (DRIVER'S SIDE SWITCH)
         Using an ohmmeter, check continuity between specified
terminals with driver's side power window switch in specified
position. See POWER WINDOW SWITCH CONTINUITY TEST table. See Fig. 1.
If continuity does not exist at specified terminals, replace power
window switch.
