1998 Signature. 30,000 miles. My problem is similar, but with a twist. I hope someone can help. All of a sudden I heard what I thought was gas sloshing around in my gas tank tank. Never heard it before, and thought it very odd. Well, after a bit of investigation. I realized my right rear door was filled with water, and that is what I was hearing. I pulled off the door panel and stuffed towels into it, and I got all the water out. Front floor board bone dry. Rear floor board bone dry. Could this be just a variation of the same leak? Has anyone had this problem? Any help would be appreciated. Thanks.
