I had the same problem. It's not the heater core that's actually located in the center by the transmission hump on these cars. My leak was coming from the gasket on the "cabin filter". You have to remove the windshield wiper arms and plastic trim to get to it. Basically you have a fresh air door that opens when the car is shut off. The Cabin filter sits above this and the rain is kept out by the gasket. The gasket is just sitting in place and mine came loose. I put it back with a weatherstripping adhesive. Haven't had a problem since.

If steam is blowing out when the heat is on, the heater core is leaking into the car. If water drenches the floor after running a lot on a humid day, the condensate drain tube is plugged. It is a rubber tube flattened on one end connected to the air box half mounted on the firewall under the hood. Check the coolant level in the radiator to make sure it is at the correct level. If it's not, then suspect a leaking heater core.
It sounds like you're looking at the heater core water lines. These connect to the heater core supply and return inlet and outlet pipes to bring hot coolant into the cabin for heat and windshield deicing.
The heater core is a mini radiator and operates on the exact same principles as the radiator does. The heater core is located behind the dash board on the passenger side. Look for a wet spot of antifreeze on the passenger side floor area - close to the firewall for an indication of a leaky heater core. If it is leaking, it will likely need to be replaced. This can be a pricey repair.
Drill a 3/8 th hole through the floor at the lowest point then look for the water leak ,is the AC drain pipe clear as this is the most obvious point of entry and the AC condensate will run into car if this pipe is blocked
I had the same problem with a 1994 Taurus. Within the front fender was 10 years of pine needles and leaves blocking the drain backing the water up in and over the fire wall and into the front passenger seat floor. I took a LONG pair of needle nose pliers threw the passenger side door, and was able to remove enough debree. After pulling out out about 5 fist full's of yuck, 1 gallon a water that was stuck some where poured out flushing out the drain. I did the same on the drivers side. After that I had no problems with floods. I hope this helps. If not check your back door weather stripping if you have one. I have heard water leaking behind the passengers seatbelt and onto the floor from under the seat. Got to love Florida's rain season(s)
drill a hole through the floor as a quick fix ,if it gets in let it out ,then check for the leak ,try under the firewall where the AC drain pipe is ,it could be the same pipe for drain water coming in from air intake vents
the vent for a/c is block and leak inside it suppose to leak outside open the hood on the fire wall on passager side at the bottom you should see a rubber hose clean that hose its full of dirt you probably see water leak out that condensation from the evaporator (a/c) system hope its a fixya thanks pierre
