I have a w220 s500l. My passenger front door controls don't work. I can't open window from passengers door nor drivers controls. Can't move passenger seat using the door controls but can adjust the seat using the rear passengers controls. The mirror works fine. I recently had 2 replace the drivers door control module as nothing worked. That fixed everything apart from passengers seat and window problem. Will this likely be due 2 a faulty passengers door module???

 

I may aswell just buy a module & find out. Got a couple of things to check but if I'm honest I hate electrics!!! I'm a panel beater/fabricater/painter. Lol.

 

Does anyone knows if a door module needs to be programmed, or can I install a replacement and everything will work as it should with out going anything???

 

as long as you get the proper one it will plug and play with no programming
