The window regulator is the component inside of your door that actually makes your window go up or down. The regulator consists of several moving parts that work together to lift or lower your window. Like most items that contain moving parts, eventually these parts are going to wear out and need to be replaced. If you have noticed increased resistance when rolling your windows up or down, you might want to look into a replacement regulator. When choosing a replacement you can count on Magneti Marelli window regulators.
