If you peel back the carpet you can see where the elbow is for the drain to the right of the gas pedal plate on the firewall. There is a foam gasket there that keeps the water from coming back into the car. Over time it gets hard and stop sealing and it will leak. You will probably see the water trail from it leaking. Also, you can drill a hole big enough for a coathanger to go into if you need to forcefully swab out the hole, just use a screw and some black rtv to seal it. You can go through the mess of replacing the gasket. Pulling the dash, pulling the heater lines pulling the a/c lines and replacing it OR you can clean the area really really good and use black rtv to seal around the tube/firewall. Option 1 takes 5-6 hours option 2 takes an hour and makes a mess but works pretty good and is significantly cheaper. The foam gasket is about 10$ lol There is also a TSB about the body seal not being that great under the carpet about where the center console begins but I have yet to see one leak there. The fix for that is to use black rtv to seal it.
