Water leak

I had this problem and it was the weather stripping right above the cabin air filter. Follow the instructions detailed in the owners manual to change the cabin air filter. You will probably find the weather stripping just laying there. I used a marine caulking and adhesive and glued it back in place. But, there was a lot of water in my carpet pad, and I had to remove the front and back seats and let it dry for a couple of days.
