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.
Driver’s power window switch has “ONE TOUCH”
function for driver’s side window.
This function opens driver’s side window fully by
just setting the switch to “AUTO” position.
When lock switch on driver’s side power window
switch is depressed, battery voltage to passenger’s
power window switches are shut off. So, even if
these switches are operated, power window motor
does not operate.
