We had a heavy rain last weekend and I noticed water leaking in at the top edge of the left rear side window in the cargo area (see the photo). Water was dripping from the top interior seal of the window in several places. At first I thought it was the seal on this window, but could it be coming in from elsewhere on the roof? The rain was very heavy, is it possible the drain system for the roof is clogged somewhere? I noticed that the right rear side window also showed some past water streaks on the inside of the glass, but no new water from this rain.

Any ideas? The vehicle is now out of warranty and I'm not sure if there's a tech service bulletin for the problem for Land Rover to cover any repairs.
