Circuit Operation
WARNING: This page is about a different car, the 2008 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.
The ETACS-ECU turns on the power window relay to activate the power windows when the ignition switch (IG1) is turned to the "ON" position.
The front power window motor (LH) receives a signal ("UP", "DOWN", "AUTO UP" or "AUTO DOWN") from the front power window main switch and controls the driver's power window.
power window motors raise and lower the door windows when the front passenger's or rear passenger's sub switch is moved to "UP" or "DOWN" position.
When you operate each power window switch for front or rear passengers (incorporated in the power window main switch), the corresponding power window motor operates, opening or closing each power window.
