2012 Prius C Wet Front Passenger Floor

My wife's Prius consistently is saturated on the front passenger side floor. All signs on YouTube and this forum seemed to point to a clogged AC line. I pulled back the carpet and the line was not clogged, it was blowing air out, but no water. I tried sticking a plastic straw up the tube, no gunk, and it made it back to the plastic housing. I let the car run with the AC on full blast for about 5 minutes and didn't see any water coming out of the rubber hose and didn't see any water dripping onto the carpet. The foam under the carpet near the hose didn't feel wet either, so I'm not confident I've found the source of the leak.

At this point, I think the hose is fine and I either have an internal AC leak, or the water is coming in through another source. It has been rainy lately and I've seen some posts to this effect, but not this specific location.

I'm including some pictures to show the rubber AC tube and the plastic box it's running to.

A few questions:
-How long do I need to run the AC before I see water coming out of the rubber tube? If nothing's coming out of the tube then I'll know it's going somewhere and can confirm an AC issue.
-If the water is never making it to the tube, where is it going? Is it possible to reach the middle of the carpet without any dripping/soaking the foam around the rubber tube?
-What else can I do to troubleshoot this? Can I remove the rubber hose where it connects to the plastic housing and spray AC cleaner directly in at that point? (this is the thread I'm getting this idea from: How to Fix water leak onto passenger floor (w/ pics) | PriusChat )

Edit: I did change the cabin air filter a couple months ago. Not sure if there's anything I could have screwed up in that process that would impact this.

 

Thank you both for your replies. Some new information, this issue is affecting both the front passenger side and front driver's side, which led me to focus on the sunroof drains (car is parked outside under trees).

I cleared out the sunroof drains with some insulated wire and compressed air this weekend. I was able to test them with a water bottle and they were both draining pretty well.

I also popped the hood and used compressed air to clean out some plastic grates that were pretty much completely clogged. I think this might be the area Leadfoot was referencing.

The only thing I haven't been able to confirm is that water is draining out the AC hose as intended. I'm going to keep monitoring the water level and see if any progress is being made. Hopefully one of these two things fixed the issue.

I don't think it's the windshield because the car didn't have this problem until recently. We've owned it for a couple years now and haven't had the windshield replaced, as far as I know, it is a factory original windshield.
