I have taken the hose coming from the ac and blew through it and it was not obstructed. It is not the heater core I believe because it doesn’t smell or look like antifreeze. Anyone have any ideas on what it could be or how to fix. It’s just on area in the passengers side that is about 8”to 10” around. Haven’t seen any weatherstripping leaking either. I’m stumped.
Water in floorboard “Help”

I am currently dealing with the exact same issue. Ruled out the AC Drain.
Things to check:
-AC Drain
-Sunroof Drains
-A Pillar holes (holes beneath the weather stripping beside the windshield exterior. Sometimes some holes exist there are are not filled when a windshield is swapped)
-Holes in the actual floor ***(my issue)
I checked the first obvious ones, AC Drain, Sunroof. All drained properly.
I pulled the carpet up and kept looking. The front section of my carpet was wet (where it angles up towards the firewall.) So I figured it was coming from above that for the water to get that high.
As I poured water down the passenger side of my windshield trim (outside) I was able to see a few small trickles of water come into the passenger floor from the front angled section.
I pulled the carpet up a bit further, poured water, then tried to trace the water.
What I found were two small "holes" where water was trickling through.
The first one was halfway up the angled piece and seemed to be either an old seal or a small rusted hole.
The second one was further up that piece and tucked way up behind the piece of black padding fabric that runs up behind the dash. I could barely get my phone camera up to see the spot. Again looked like a possible small rust point/failed seal or leaking bolt.
As the water was poured down the A pillar it ran into the engine bay, then ran down behind the engine. Looking from the wheel well there is a pinch weld (I think) where the rear mud shield attaches. On the inside (engine bay) of that piece where it meets the firewall I could just see the two suspect points. Couldn't get my head in there but my camera could just see them. The water ran right over top of these points and trickled in.
I put some sealant on the inside of the holes and am having my shop take a peek this week to hopefully get a good amount from the outside.
Consider taking a look under the carpet and running some water down the A pillar (outside).

SOLVED!!! Water in driver's side floorboard
So, I have read over time where many have posted about water being in the driver's side floor area. There have been a number of possible causes like plugged sunroof drains, plugged drain holes etc.
I found a solution to my "water issue" and it may help. Underneath the carpet on the driver's side floorpan, there is a round, rubber plug about two inches in diameter. Just looking at it, it looks fine. I decided to swap it out with one I pulled from a parts yard and covered it with gorilla tape. Low and behold, the water-in-the-floorpan DISAPPEARED. Carpet is dry as a bone even in this torrential rain we are having. Hope this helps someone out.
Seems like this plug shrinks over time and water gets in. Rather than replacing it, it might work to take it out, clean it and put some silicone caulk around it and then cover it in heavy-duty tape just to make sure it stays put.

It was sunroof drains for me - put a ton of water in my carpet.

where are the sunroof drains & whats the proper way to make sure they are clear?

If you open your sunroof and look at the front corners of where the glass goes. There is a small hole on each side. You could blow some compressed air down them if you needed but just pour a little bit of water in and watch for the water draining behind the front tire.
If not water drains out then that could be your issue.

Some threads that might help direct your troubleshooting:
Passenger side floor wet
Passenger-side carpet wet
passenger floor soaked
Wet floor????
Wet passenger floor? AC drain line?
Wet Carpet Passenger Side Front when it rains

Did you ever fix the water issue with this? Did it ever come back? I've done sunroof, AC, now I'm moving onto A Pillar and your pinch weld suggestion. Almost at wits end.

I did sort it out but the solution probably doesn't pertain to you.
My vehicle has a rebuild title as it was in an accident on the front passenger corner.
I believe this was the issue but it opened up a small seam/cut in the firewall that water was dripping into. Begin the fender where it connects to the firewall there was the small little hole that water would drip through when it got wet.

I was getting a puddle after each rain. It was the sunroof drains. The two front drains were completely covered with mud. I cleaned it out and then snaked the tubes with a combination of electrical wire and some of my son's 3D printer filament. I haven't snaked the rear drains, but so far so good.
Ah gotcha. It rained hard here last night and I was worried about what I'd find this mornng but to my surprise the floor was bone dry. I guess whatever it was I found it. Feels good.
