My newly aquired car had water in the spare tire well when I bought it. Dried everything out and left the rear trim panel out, but bith side panels are still in. Car sat in a light rain and the well stayed dry. Ended up driving through a moderate rain, and when I stopped there was a little water in there, so I don't know if it was from rain or road splash. It looks like the origination point is in the far rear of the well, under the jack, but I am not certain. I have not yet located the sunroof drains. If this is the problem, how does the water get from the drain into the well? Is there an origination point at the far rear of the well, or do I need to keep looking?
