Water Leak in the Trunkish Area

[BMWredneck]

Im trying to pinpoint a small leak in my trunk area. Actually i know its coming from the area right behind my backseat. Its just i cant find the leak. Could the little rubbers on the side windows be leaking to the center of my car?
Also the water is not like puddles or lakes, its more like condesation when i pull up the carpet and then some weird pad thingy. Its right behind the backseat.
Or is this such a minor thing that I shouldnt even worry about it?

Also on a completely different subject, does anyone know how to change the Belt tensioner pully for the drive belt? I just need to change the pully not the tensioner and hopefully that takes away from a lotta squeak up front. I did check the bearings in it, and it has a good amount of play up and down and side to side, and a little in and out. But i cant get the bolt to move in either direction and Im scared of breaking the bracket off. Thats the last thing i need to happen.

Have you looked at your rear shock mounts lately? The metal could be cracked.

It's just condensation. If there are no puddles then don't worry about it. When you drive the car, your heat is warming up the interior. Then you park it and it gets cold because lets face it, that's what happens in winter. Condensation forms on the metal under the carpets. Totally normal.

I think you also need to change the whole tensioner.

+1 On checking the rear shock mounts. Especially if you hear knocking noises from rear of car.

nope the rear end is tight, its my front end that needs looked at haha.
And if i have to replace the entire tensioner then that sucks. cause that means pullin some other pulleys off to get to some bolts looked like.
