After driving in through heavy rains with the A/C on for almost 7 hours, we arrived at our destination and parked our 2001 Camry LE (41K) for a week. Upon returning I noticed that in addition to a small wet spot on the driver's mat by the gas pedal, the carpet and mat behind the driver's seat was soaked. We don't think a bottle of water opened by mistake. Could this be related to the A/C? If so, how could it get so wet in the rear seat area? What's going on here, and how can I fix it? Is it more likely there is a hole in the body or chassis? There is no visible rust on this car so I don't know why there would be a hole. Any ideas? Thanks!
