Power windows are a feature in many modern vehicles that allow passengers to open and close the windows with the push of a button, rather than using a manual crank. This system is powered by an electric motor, making it more convenient for drivers and passengers to adjust window positions quickly and easily. Typically, the controls for power windows are located on the driver's door panel, allowing the driver to operate all windows from one place. Some vehicles also have individual controls for each window, providing flexibility for passengers. This technology enhances comfort and accessibility in cars.
