The AC condensor is just like a glass of cold water on a humid day. The moisture in the air condenses and then it runs off the evaporator coil and out the drain onto the road.
If the drain tube gets clogged, the box that the evaporator coil is in will fill with condensation. On a very humid day, this can happen at a surprizingly rapid rate!
Once the box fills to a certain level, it begins to leak onto the floor of the car.
After driving for 1/2 hour with the AC on, I have 1" of water on the floor in the back seat!
