Water leak on floor, not sure how to fix

[zapattack]

I have noticed a small amount of water has been getting inside my cab when it rains, it's not the window seal, it seems to be coming from inside the passenger side quarter panel inside where the air vent is under the dash. I attached some pictures for reference. Was wondering if anyone on here had this same problem or knows how I can fix it. Thanks.

90% chance cleaning out the built up organic materials down in the cowl drain, which I think? is your last pic, will cure the issue.
Cowl cavity should drain out freely on each side.
If you fill the cowl with water and it’s leaking in where you show, that’s the most likely cause.

You need to clean out the bottom of that vent bucket. It should be open at the bottom to let it drain.

You must be registered for see images attach

Use a vacuum or a poker and some water to get it broken up and flushed out. Also make sure your cowl vent screen is in place and not broken up.
