I bought a 2012 Ford Escape that has had some leaks in the sunroof. I have found lots about blowing out or different methods for cleaning out the front drain tubes, but people mention the rear drain tubes, but you can't really get to them. Another person on UTUBE showed how he cleaned them on his BMW suv, by working from under the car and backwards with a weed whacker line or some other stiff wire. Before I start to dig, I would like to know if any one knows where the rear drain tubes exit the car (on the bottom) so that I can try to run a week whacker line up it, since I can't really find it in the top either, and have no intention of pulling my head liner! I'm sure I'd break it doing it. A picture would be enormously helpful if anyone had one!
