I have question about my Chevy Tahoe '12 LT. Couple of days ago we had a huge rain. Next day, when I was driving, I was able to hear a clear sound similar to "splashing a water in half-full big bottle". I stopped and went around the car. On right side, right between front and back passenger's doors, there was a steady leak of water. I have checked inside the cabin for any water and found none. No smell either. Anyone have any ideas what I am dealing with? Thank you.
