Somewhere in this forum, recently, there was a great post about this very thing. I think you need to pull back the passenger footwell carpeting back a bit (below the globe box), and you will see the hose that runs between your evaporator case and the floorboard. Most people said there was debris in the hose that they needed to clean out, and nothing leaked after that. You will have to do the searching to find this thread, but I'm pretty sure it was in this exact forum.
