Evaporator Drain Tube..
 

I have a severe water leak coming down both foot wells from under the dash whenever I run my A/C. I've finally removed the carpet and dried the entire interior. Now I have been trying to locate the evaporator drain tube.
There are some videos for other Scion models but no information on the IQ. Behind the evap and under the dash is very cramped and even with multiple panels removed, I cannot find this drain tube. I see the location under the car but cannot trace it to the interior.

This is the closest I've come to the location of your drain tube:

Thanks Craig, I replaced the filter a few months back. Took it out and it was fine. Managed to find the drain tube, it's a spout in the engine compartment roughly in the middle at the bottom of the bulkhead. Could just about see it by looking diagonally down to the left from the Battery. Tried to take a photo of it but couldnt get it to show up.

I jacked the car up on the passenger side and there was water dripping out of the spout. Thought (hoped!) jacking it up may have sorted the problem but it didn't, the water was flowing into the drivers footwell instead. Going to have to take a trip to the garage to see what they say.

The above link is four pages long. There may be more posts regarding the drain hose location. There are also responses dealing with non-AC related leaks that result in water on the floorboard(s).

Good luck finding the leak.

Holy ____. Don't know how you found that but I appreciate it. I've been idling with the AC on today and watching for water. That thread is scarily similar so I'm going to try the drain extender. This is my 4th car in two years so it's a little traumatic when issues like this come up. Usually it means a few more things break and the problems outweigh the cost.
