Window lifts are mechanical devices used in vehicles to raise and lower windows. They can be operated manually or electronically, with the latter being more common in modern cars. Electronic window lifts typically use a motor and a switch, allowing passengers to control the window's position with ease. These systems consist of several components, including the window regulator, which helps guide the window's movement, and the power window switch, which activates the motor. Proper maintenance of window lifts is essential to ensure they function smoothly and prevent issues like window jams or failures.
