The Perodua Alza Power Window Switch is a component of the car's power window system that allows the driver and passengers to control the windows. It is typically located on the driver's side door panel, but may also be located on the passenger side door panel or on the center console.

The Power Window Switch allows the driver and passengers to raise or lower the windows with the push of a button. In some cars, the switch may also include an automatic window function that allows the window to be raised or lowered with a single push or pull of the switch.

The Power Window Switch is connected to the car's electrical system and sends an electrical signal to the window motor to control the movement of the window. If the switch or the window motor fails, the window may not function properly or may become stuck in a partially open or closed position.
