Power Window
General Description
The circuit consists of (door lock &) power window
switch for each of front windows, power window
switch for rear doors and power window motors.
When starter switch is turned on, battery voltage is
applied to each of power window switches through
circuit breaker and power window relay on the
circuit.
DriverÕs power window switch has ÒONE TOUCHÓ
function for driverÕs side window.
This function opens driverÕs side window fully by
just setting the switch to ÒAUTOÓ position.
When lock switch on driverÕs side power window
switch is depressed, battery voltage to passengerÕs
power window switches are shut off. So, even if
these switches are operated, power window motor
does not operate.
