rain leaks

Both port and starboard fixed side port lights, rear positions leak from the bottom rear corner. Has anyone made this repair?

My main cabin fixed windows/ports on both starboard and port, rear position, leak at the lower rear corners. They have a bezel on the inside attached with phillips screws. I have tightened these, did not help. I was in another 08 ds that did the same thing, so I think this is a common problem...
