Power Window

General Description

The circuit consists of the starter switch, power window switch for each of the windows and power window motor.
When the starter switch is turned on, the battery voltage is applied to each of the power window switches through the
circuit breaker and the power window relay on the circuit.
By operating the switches of each window to select “UP” or “DOWN”, the revolving direction of the power window
motor changes to open or close the window.
The driver’s power window switch has a built-in one-touch operating circuit which allows to automatically open the
window by operating the switch to the AUTO position.
When the driver’s power lock switch at the driver side is depressed, the power source to the passenger’s power win-
dow switches will be shut off and passenger’s side power window motor will not operate if the switch is operated.

Notice:
Arrow marks indicate the direction of current.
