My 2003 E 500 stopped being able to open and close the windows with the smart key (the summer opening feature). Its when you press and hold the lock button on the key and point it to the drivers side lock and it would close my sunroof and lock my doors and would close opened windows; and vice-versa when you unlock. I noticed it "only works now from the passenger's side lock" as I press the button on the key, not the driver's side as it used to. Maybe a sensor not working? Help please?? :bowdown:

I guess you mean it works on the passenger side but not on the driver's side? If it works from one side but not the other, I cannot see anything else possible than the IR sensors being faulty at the door handle. Theoretically some wiring but quite unlikely.
