Hi there. I have a '95 S350, yesterday I tried to open the rear right door and it wouldn't open. Then I tried all the other doors, and they oppened. Can you please halp me with this as soon as possible. And another problem I had a leak of the A/C fluid five months ago which I replaced, but when in turn on the A/C I hear this noise which sounds like when the the vacuum assist pulls the doors, the sound that comes after the doors are pulled.

The first problem is very important to me right now.
