Question Fluid leaking into the inside of my rx300

I have a 99 rx300 and it all of a sudden started leaking fluid under my floor mats in the front seat. It makes my windows fog up, thats how i caught it since the floor mats at so thick ( the floor mat itself is dry) It doesn't have a chemical smell to it. My car isn't over heating, I am not sure if there is water leaking in because something is backed up. origianaly I thought it was the heatercore, but with it not over heating and not smelling like coolant. I'm just not sure.
Any advice???? Help!!
Never had anything go wong with it, so not sure where to start.

You can probably tell pretty easy by just pulling the carpet back and pulling the hose off. If there's no buildup of water, it's probably not the hose clogged. Take a paper towel and when you pull the carpet back, if it's wet enough, try and absorb as much as you can and then smell it. You should be able to tell the difference in the smell between water and anti-freeze. NORMALLY, water will not fog the windows in the same way anti-freeze does, but the weather conditions in Wa. might cause it to. Hope it's the drain hose.

Default Water leaking into my RX300

I have the same problem and I'm not totally sure how it happened. There has been crazy rain and some pretty big puddles here in WA state over the last few days. Does anyone know if there are some common leak points on the car. Either on top or underneath? The entire passenger compartment has a decent amount of water in it. We are definitely going to need to strip down the car inside to let it all dry out. All of the door and window seals appear to be in perfect condition. My fear is that we strip the carpet out and let it dry out and this happens again. Any info would be much appreciated. Thanks so much.
