How do I fix wet front floormat on passenger side?

Howdy,

My wife showed me tonight that there was a good 1/2" of water in the front passenger foot well of her 2002 Prius. It seems to be fresh water, not antifreeze.

We've had lots of rain recently, but it didn't rain tonight when I went for a test drive, and more water appeared. More telling, I think, is that we've just now begun using the air conditioning. I'm guessing that's the problem.

I've read that other cars have a faulty drain for A/C condensate, so maybe that's what's wrong here, too.

Does anyone know how to fix this? I don't see where the water is coming from. Where is the drain line?

 

Nate, I think I heard Click & Clack suggest using compressed air on the drain, too. I wonder where the material forming the clog goes? Maybe once it's packed into a dense blob, it's less likely to move back into the tube after you blow it out?

 

Thanks for your advice, Nate. You are so right! When I looked into the black drain tube, I could see something white that looked like an insect's work, a spider's nest probably. I poked at this with a wire to remove it and a trickle of water came out. Then I blew the drain tube with compressed air and a torrent came out. I didni't realize that so much water was stored in there!

In case anyone else has to deal with this, I'll detail what's involved.

Location in the car
There is a black rubber tube that you can see come down from somewhere in the center console to a hole in the floor on the passenger's side.

Location under the car
Under the car, the tube pokes out no more than 1". It appears a few inches toward the front of the car from the flat area of the passenger's floor pan. It's just behind a ~5/8" black solid beam that I assume is part of the suspension. You can miss the drain because it's behind that bar. The drain is about 4-6" to the passenger's side from the exhaust system and just in toward the center from four black metal gas (?) lines.
