It is a single unit, which serves to create the required force to move the window.

Lifting mechanism is necessary to provide the window travel. Depending on the design of this mechanism, there are several types of window lifters - cable, lever and rack. Regarding the most frequently used mechanism in modern cars, manufacturers mainly prefer cable and lever. It should also be said that modern electric window lifters have two types of control systems - direct and electronic. Direct control is a fairly simple design. It is implemented by three-position switch, which is included in the power circuit of the electronic engine. When the switch is moved to the first position, the engine rotates in one direction, when to the second position - the polarity and direction of the engine rotation change.

Electronic control is much more complicated. An input device, electronic control unit and execution unit provide its operation. Failure of the window lifter can result in inconvenience in terms of safe operation of car and comfort ensuring.
