If begain with the front pasenger window not working and progressed to all windows, door locks and power seats
In icy weather the remote will not unlock doors. In warmer weather the remote only unlocks the driver door and the right side rear door. When you use the remote to unlock, you can see the front passenger side door lock move up very slightly but not enough to unlock the door.

Why is this problem caused and can it be fixed easily by me or do i need to take it to the MB dealer ?
Passenger front door module failed. I found a good used one on eBay and had a shop replace it. Shops do not like to put on parts they don't sell to you. I suspect there is a lot of profit in parts. The repair shop said they would no do another repair with parts that I supply.
passenger side windows, and front passenger seat adjustment don't work properly. can operate the windows sometimes, and sometimes not at all. recently, the front passenger side window started sliding off in a an angle. i have not yet taken my car to be fixed.
