work at all by operating the power window main switch.
.
CIRCUIT OPERATION
When you operate each power window switch for
front or rear passengers (incorporated in the power
window main switch), the corresponding power win-
dow motor operates, opening or closing each power
window.
.
TECHNICAL DESCRIPTION (COMMENT)
If the corresponding power window opens and closes
normally when each power window sub-switch is
operated, the power window main switch may be
defective.
.
TROUBLESHOOTING HINT
Refer to circuit diagrams GROUP-90
Refer to configuration diagrams GROUP-80
The power window main switch may be defective
