BMW 740iL Window Regulator is the mechanism that actually does the job of raising and lowering your window glass when you push the button. A window regulator is a fairly complex piece of machinery containing many components. These include a worm gear (also called an Archimedes Screw), several spur gears, linkages, a mechanical plate and the bar that supports the window glass.

This elaborate set up of worm and spur gears is activated by a crank, which raises a mechanical plate, upon which sits the window glass. As you might imagine, window regulators are used constantly, every day that you drive your vehicle.

Like any piece of machinery that gets a lot of use, it will wear out and eventually cease to function.
