Leak on passenger side flooring

Hi all
Spent yesterday pulling the carpet and removing the cowl to determine where this leak is coming from. Drains do not seem clogged but water got in behind the glove box. Filter was saturated as was the passenger floor. Happened during a week of rain. I put the cowl back, rain water over the windshield and water is draining as it should. What else should I check or where else could this leak be coming from? Want to put in fresh carpet but not until I'm certain the leak is gone.

 

I had a wd21 Pathfinder that had a leak. I just sat in it during a pouring rain with everything torn apart to see where it was coming from. Only way to find it.

 

Took me a few tries to find my leak. My cabin filter was dry but water was running down the inside of the cowl and pooling under the passenger's feet. See post #14.
