Water in rear quarter panel Options

[pepsiman]

I was taking out my antenna about a few weeks ago and water was standing in the space beneath it. There is a little hose going from the antenna to the outside of the car that was stopped up but i dont think it would have anything to do with water draining from the car so whats going on? im guessing water is not saposed to be there so do i have a drain clogged up or what? I been under the car looking for a drain and dont see it Ive been looking abot from the mudflap back can anyone help out? kinda sucks i dont want it to rust

I think i got it fixed i tightened the silver thing that screws onto the antenna mast where it meets the quarter panel and i cleaned out the little drain hose. I left half of the fasteners out that hold that trunk plastic in though so i could keep a eye on it from time to time. I really dont think it will leak since i sprayed a water hose right on it but im just paranoid lol

Thanks for all the replies
