There are two basic kinds of window regulators: manual window regulators and power window regulators. Both types does basically the same thing, that is to lift up and down your car windows to whatever position you want it to be in. But while they do the same basic things, the process of doing such thing differs for the two types. For a manual window regulator, you have to exert an effort to lower or raise the window, while for a power window regulator; this process is dealt with electronically and can be done with just a click of a switch or a button.
A typical window regulator is composed of several components that include a worm gear and a combination of spur gears, a mechanical plate, and a linkage. The linkage supports the window while the mechanical plate is responsible for moving the window up and down. The precise movement of the mechanical plate is controlled by the worm gear-spur gears combination. For the manual window regulator, a crank that is manually controlled by person using a crank handle controls the worm gear. For the power window regulator, on the other hand, an electronic motor connected to a particular electronic module on the car controls the worm gear.
