2028204226 Mercedes W202 W124 Comfort Window Sunroof Module – OEM Used & Tested

Описание

This Mercedes comfort window and sunroof module is a genuine OEM electronic control component for the Mercedes W202 and W124 models. Primary OEM number 2028204226. It is designed to control the comfort functions of the power windows and the sunroof, allowing them to be opened or closed together from the lock or the remote control.

Its job is to receive the comfort command from the central locking system and to drive the window and sunroof motors in the right direction until the end position is reached. It also uses the signals from the window switches and the door contacts to stop the movement safely at the end positions. A properly working comfort window sunroof module supports convenient ventilation and closing of the vehicle, protects the interior from rain and supports correct operation of the comfort system.

Common signs of a faulty unit include windows or a sunroof that do not close from the lock or the remote key, comfort opening that no longer works, a sunroof that stops moving or moves in only one direction, or windows that react only from the individual switches. When the module fails, the comfort function may be lost and the windows and the sunroof may have to be closed manually.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 2028204226 before ordering. Professional installation is recommended, and a check of the window and sunroof motors and wiring and a basic setting or initialization of the end positions where applicable should follow installation.
