Hey gang.

I've been getting water in my trunk when it rains. I've read hundreds of posts about this apparently common problem. I even found a shop that would install a new rear window seal for me and keep my current glass. Before I do that though, I want to make sure that the rear window seal is the culprit. I've poured buckets of water all over the rear window with the trunk open and no water enters the trunk, so am I missing something?

To clean the water out of the trunk today (because of yesterday's rain storm), I removed the 2 plastic wheel well inserts and the wall against the gas tank. When I removed the top screws from the wall, water came pouring out of the screw holes. I noticed that the screw holes are in a part of the body that looks like a metal bowl with drain plugs. What are these? Why does water go there? I can only assume the water is not meant to just sit there, so where is supposed to be going?

Any insight would be greatly appreciated.
