Hey guys, I have water leaking on my passenger floor. I had my battery drains redone on warranty by the dealer a month ago and it still goes on. I went under the car and put my hand thru what looked like the plenum drains from what I was told and they were clear. The sunroof is always closed, so I guess it wouldn't be that, but I guess I could always check.

What I am left with now is the A/C evan drains but where is that located?! What do I need to take off in order to get there and unclog it because it's bad now and it started smelling bad.

Thank you guys!
