Water in the rear vents

I found that the rear floorboards were wet this week and started cussing, thinking that the door vapor seals had failed again. While coming back from an event with the kids in the back tonight, I gave it the beans a bit and my daughter exclaimed that a bunch of water poured out of the rear AC vents behind the console. Sure enough, I put my hand back there and the top of the tunnel was soaked. It has been hot and humid the last week, not sure I can do anything about this. Anyone else see this or know what can be done to avoid it other than not running the AC when it is hot? I'll put a some plastic down with a towel on top in the near term but I would think that others in the terminally hot and humid states would have run into this before.
After thinking about it, one thing that could be contributing is that I don't think the environmental control is working correctly. It doesn't seem to regulate the temp, just blows really cold and only way to regulate it seems to be with fan speed manually. If that is the culprit, where do I start?

Check the evap drains under the car perhaps. They can clog or collapse.

Those are the two tubes that are at the transmission underneath right? I don't think they are clogged because I do get a puddle after parking and having run the AC but I will confirm.

There are two tubes under the tranny, and they are separate, IE one could be plugged and the other would not drain it. I had this and got water in the front. Might have been in the back also never noticed. Sorry my memory again there was something strange about the tubes think it was a flap or something that prevented air from being blown up them. I think I used a snake and broke up the bug nest in the one tube. Anyway I am sure you will figure it out.

Yes, what sailor mentioned. I wasn't able to answer earlier. Be careful cleaning the tubes out, if they are clogged from the evap side, then you're dealing with bacteria, not road debris or critters.

At times, I've used the 1Z Klima Clean from under the car and ran the provided hose into the tubes, using the entire can. This works some of the time to at least disinfect before I clean the tubes.

Well, I needed to get under the car this weekend anyway to start dealing with the sill rot so I will snake the drains. don't want to back blow them and soak wherever under the dash the evaporator/exchanger is. I found the two drain pipes in Real OEM but there isn't any pictures to show where they are draining from.
