The mechanism that moves the window up and down is called the window regulator. In cars with power windows, the window regulator is powered by an electric motor, called the window motor. In some cars, the window motor comes with the window regulator as one unit; in others, the window motor can be replaced separately.
There are two basic types of window regulators: the gear-drive type (in the photo) and the cable type (see photo below).
In a typical sedan, there are four window regulators; one inside each door. In some convertibles, a separate window regulator can be installed inside the rear quarter panel. A window regulator doesn't need any maintenance or adjustment. If it fails, the failed part or the whole unit must be replaced.
Window regulator problems
Problems with window regulators are common. A broken window regulator cable can cause the window to jam or fall down inside the door. See this example, where the cable broke and the power window stopped working. In cold temperatures, the window can freeze in closed position. When the window switch is operated down, the window can separate from the window regulator. If this happens, in some cars, the window can be re-secured without replacing parts, in others the window regulator might need to be replaced.
