Water build up behind passenger seat
 

I have the strangest problem. I seem to have a natural well right behind my passenger seat. The drain plugs don't seem to be clogged, what should I be looking for?

Check to see if the foam that drains down to the drain plugs is cut.

If the top has ever been worked on and they were not careful -- that foam gets cut.

I remember it being pretty pricey -- I fixed mine with a little RTV.

Did you actually pour water down the drain holes to see if they do indeed go where they are suppose to? That's what I would do. If that is ok then I would start spraying the car to see where the water intrusion is coming from. Even pull up the back carpet and maybe even the seat to track it. Just remember if you pull the seat to disconnect the battery otherwise the SRS light will come on and wont come off without the proper tool.

This is a good suggestion. I had a similar problem in my wife's BMW 325i with water intrusion into the passenger rear seat footwell. I sat inside while she sprayed the car with a hose and we found that the passenger rear door seal was leaking. Seal appeared to be in good condition visually but obviously was not making a good seal. Never would have found it any other way.
