WIRING SYSTEM

Power Window

General Description

The power window system consists of power window
switches, power window motors and power window relay.
With the starter switch in “ON” position, the battery
voltage is supplied through power window relay to the
power window switches. Selection of up or down switch
changes over the motor rotating direction to open or close
the window.
When the lock switch on the switch panel on the driver
side is pressed, the power window switch is in open state.
As a result, the power source to the other switches are cut
off, and the power window motors do not run.
