Mercedes s class w220 door control module replacement or driver's door switch replacement.

Hi guys this vidoe shows any mercedes W220 owners how to replace this common faulty driver&door control module (DCM). Nice, simple and fast DIY replacement without needing a mechanic. Many of these mercedes s class w220 models suffer from the driver&switch/ door control failure. This just happens out the blue especially if you have had your windows tinted, water might get into the switch and you wont be able to open the driver&window nor both rear windows. You also can&adjust or fold/ unfold the mirrors. Only the front passenger window will work as it uses its own bus system.Thanks for watching.
