I had one leak where rain ran down the outside wall and entered at the trim line along the bottom of the slide. It followed the floor line inward until it dripped off of the inboard front corner. I guess that was the low point of the closed slide.
Well, it seems this was the problem. I checked the edge of the trim at the bottom and part of it had begun to pull away from the siding. I finally had a dry day and re-caulked it. We've had a couple of days rain since then and the floor hasn't gotten wet. Now all I have to do is figure out how to get rid of the mold. Thanks to all for your help and suggestions. We'll call this one a success.
