Water leak in rear cargo area
I have an interesting water leak that has me scratching my head - the rear cargo area has an area where the flashlight is (driver side) and there is a small catch cup there (where I put my hitch lock pin and little things as such) that has been filled with water 2 times now after a heavy rain. I cleared my front two drain channels in the sunroof (using compressed air and a straw), and I do not know where this water has come from. The spare carrier is dry, as is the passenger cargo area. Water doesn't typically fight gravity, so I think that this should be leaking from above, but there are not any other wet spots in the area.
Any ideas? Where are the rear drain tubes in the pano-sunroof so that I can clear these as well?
