My son has a 1997 Outback. The passenger side rear floor is filling with water. He is away at college. Today he called to say the rear floor passenger side was full of water. There is no water in the rear wagon area nor in the front. He didn't drive it today. It sat in a heavy rain all day. He has noticed moisture in the wagon for some time. He will be home next week. Any suggestions on how to locate this leak.
Thanks, Dave
