During a rain, water is pouring from the roof liner and running down the back glass into the storage trays. I am not sure if it is coming from around the Sirius radio antenna or from the rear brake/cargo light. Or it may be from someplace else but these appear to be the most logical. I tightened the screws on the rear brake light housing but that did not help. Anybody have any ideas.

Heavy rain for several hours had revealed a leak. The back seat on drivers side is soaked, and the headliner above that seat is holding water.
