Here's one I've not experienced in 35+ years of automobile ownership.

1997 ES300 with 148,000 miles, excellently maintained. Live in MD. Lately it's been VERY HOT (95+F) & very humid. When using the a/c, the passenger compartment floor gets SOAKED with water. SOPPING WET!!! The front passenger side as well gets wet. This is not a "weatherstripping" leak (my first thoughts).

Tonight, with family in car on a hot and humid evening, drove the car and used the a/c in the rain to dehumidify. While the a/c is in use, the floor of the passenger compartment becomes a small low pressure system (meteorological metaphor) and several towels must be used to soak up the water after a 15-25 mile drive when we get home. Not good at all.

We have identified that the cause is the a/c when we use it. This is obviously a problem! Has anybody experienced this, and what is the cause? Is this something I can repair myself? Need help before the bottom falls out!!! I have an OBD II code reader and get a "NO CODES" when reading the on-board computer. I am also extremely capable of performing car repairs as I do most of the maintanance myself. Help!!!!!

the only thing i could think of would be the (i think its called) condensation drain hose has poped off or is pluged or sumthing?

The evaporator drain is clogged. You can sometimes unclog it by getting under the car and running a snake up the drain tube.

Thanks for the tip on the evaporator drain plug. I changed the oil and filter, checked the tire pressure, and got under the car to complete the prep for my wife's trip to Pittsburgh. Clipped a coat hanger and measured off and marked one inch increments. I inserted it into the drain ~8in or so, and Wholaaa! At first a trickle. I teased it bit more and there must have been a 20 second flood of water that came rushing out. I estimate it was at least a gallon!

Needless to say, problem resolved. Trip went well and the a/c works great (again). My wife thanked me too (but this is not the forum) Thanks!!!

Awesome, I have the same problem with my ES300. Can you tell me exactly where this drain is and what it looks like?

Cheers.

A rubber tube or hose about a half inch in diameter. Accessed from the right side, behind and inside the right front wheel. It protrudes out from the firewall.

Thanks, I still have trouble finding it looking down from an open hood.
Do I have to jack up the car and look underneath the firewall to find it?

Could you insert it more than 8 Inch? I tried on mine today and couldn't insert any further at about twice the length of the protuding hose.
