I get a ton of water in my car when I run the AC. (I took a 5 hour trip one day and actually had a small puddle I scooped out with a cup). The drainage tube is not clogged. It seems as if there's a leek somewhere --- help!

If the swooshing sound is up in the dash area..and you have not lost any coolant.. chances are you have a plugged AC/Defroster system drain hose.
On a hot humid summer day when folks are running the AC you may have noticed puddles of water under your car and others. This is the excess moisture being pulled out of the passenger compartment. It collects and drips out of the drain under the car.
You probably don't have that puddle forming anymore.. the drain is clogged. Next time you have it in for an oil change at a decent shop.. have them locate that hose..give it a blast of air.. to unclog it.. and drain that water..
If the sound is coming from somewhere else.. best to locate it and drain it.. or clean the drain holes..doors etc..
If you have the smell of Coolant then you have a leak in your heater core. You said immediately so that is the first thing I would look for. If there is actually a bit of time before it forms I would check to ensure the drain for the AC condensor is clear as when the Defroster is on the AC unit also runs. If you think this is the problem and want a quick fix, disconnect the Wires from the AC Compressor and it should stop the problem.
Yes this is completely normal. What it is doing is condensing the moisture in the air. When this happens you have mositure build up in the cars ac system. This is needed to be drained off and is done so bay a drainage line that comes out of the fire wall of the car and allows it to drain underneath. The more the ac is used the more moisture you get.
Water puddling on the driver side (ONLY) of Endeavors is evidence of the drain tube foam seal failing. This is very common on Endeavors, and will be more evident on humid days, rainy days, especially with extended driving. The drain tube for the AC system that extends through the firewall has a small foam ring that seals moisture from running back into the car after it goes out the tube (think of pouring water out of a glass, how some always runs down the side). High humidity days will cause more condensate than normal and amplify your symptom. Rain will also make it worse, as road water will spit up to the drain hole, as well as normally enter the box through your fresh air vent, creating more water to drain. Driving speed also help force the water past the seal. The only correct repair is to remove the evaporator box (requires dash removal) and either replace the seal with a new one, or as I prefer replace it with a butyl rubber type substitute that will not degrade like the foam. You can pack butyl rubber or similar (think windshield packing) around the seal flange on the inside, but it is not an ideal repair.
If it actually is freezing up,the low pressure switch is the likely cause.It is screwed into the large ac line near the firewall,witch is the cold line.If it is not there it is in the dryer,near the firewall,or under the air filter box.Follow the ac line(large ac line/hoses)from the ac compressor untill you come to the switch,that is the easy way to locate it.This low pressure switch causes the ac compressor to cycle on and odd according to the pressure sensed from the ac low side line.When it gets really cold the pressure is lowered,and there for it will cut off,and when the pressure rises,it cuts the ac compressor back on.It would be a really good idea to check the freon in the vehicle first.If the ac system is low on freon,it will freeze up on some vehicles.
the heater core lines are under the dash and when it starts leak i will flood the floor board. does the ac shut down even if you are running it on recirculate and on fresh air. it may be the compressor clutch. if that hasn't been replaced yet.
