Window Regulators & Winders, found under Body > Windows & Mirrors, are essential components of a vehicle's window operating system for both passenger cars and commercial vehicles. These parts facilitate the raising and lowering of side windows, ensuring driver and passenger comfort and weather protection. Window regulators utilize a mechanical or electrical system - often cables, gears, and motors - to smoothly move the window glass within the door frame. Manual winders provide mechanical operation, while regulators often connect to power window switches for electric operation. Examples in this category include MAN window regulators with part numbers like 81.62645-6055 and 85.62640-6011, designed for specific vehicle models and door configurations. Ensuring proper function of these components is critical for vehicle safety and convenience.
