On mine, it was the a/c drain. Remove lower dash cover and blow out drain on right hand side of HVAC box above trans tunnel.

I am sorry I do not understand the rest of your post.

 

Did you make sure the drains under the battery tray are clear of debris? That is a common source of water int he passenger footwell. You would need to remove the battery, and remove the tray on which the battery sits to get at the drain in question.

Other sources include:
-windshield cowl not installed properly
-clogged sunroof drains
-clogged a/c evap drain

Best of luck!!!

 

Oh, and here is a post that shows you how to get at the drain under the battery tray, and contained within this post is a link on how to remove the battery itself:

Also check your Cabin air filter.

If it is wet then the plastic strip at the bottom of the windshield might be leaking. You need to carefully pry it out and clean the debris under it. Then push it back in. I used a light coating of silicone in the channel and used some black along the top where it meets the window.

Mine was leaking and dripping into the cabin air filter.

 

What ever you do fix it sooner rather than later. The transmission control module is under the carpet on the passenger side, i fried mine due to a blocked A/C drain.

 

seems to be coming from a spongey type washer just above the footwell at junction of glove box!!!
