Pontiac Forum - Pontiac Discussion Forums - 2006 Pontiac G6 Water Leak in backseat

About a month ago it rained really hard and I came out to my car to find about an inch of water on the floor in the backseat on the passenger side. Only the floor was wet, not the seats or anything else. The windows were all shut and so was the sunroof. I cleaned it as best as I could and it rained the next day and there was no water so I figured somehow i left a window open a crack and didnt realize. Anyway I woke up this morning after a pretty nasty rainstorm last night and there is about 2 inches of water in the backseat, so much that when i soaked it up there is more under the carpet and its pushing the carpet up. Its only in the back and only on the passenger side. The trunk is dry, and when i pulled the backseat up it was dry too. A friend used to work for a dealership and said that it could be clogged sunroof drains. Any help? Thank you!
