Kids... One is in a car seat the other is hardly in it. I don't allow food or drinks inside either. We had hard rain from that hurricane down south and they had it sitting outside, no leaks. My other question though ac drains water under the engine or front passenger tire and back passenger tire?
This has been such a hastle. The dealership said there are no tubes running to that seat for air to it like coolant and such. When we wash it we use a pressure washer bc that's the kind of soap we use that hooks up to it. So it gets that once a week or two. I'm so lost. I traded my 2018 explorer for this 4 months ago

Well, your narrowing down the possibilities. IIrc you said you smelled a musty smell that started you looking.
A musty smell takes a few day's to present itself. I understand one of your kids is in a car seat, is it possible that the rear side door button was brushed against when putting the kid in the seat and lowered the window a bit so water could get in?
I'm at the point that if nothing you or the dealer has done to force water in, remembering it was on the seat cushion, it apparently came in with some force. A force that can't be duplicated with a power washer. I'm going with a window inadvertently opened a bit and wind driven rain coming in or a door not fully closed.

I'd say they forgot to install a plug somewhere at the factory, it happens. They need to take down the headliner and investigate.

The fan only cooling works great. Completely adequate, and never leaks. The rear seats have no ventilation, so double NO for that as a possible cause. I liked the headliner/paper towel idea. Just out of curiosity, is your AC drain letting water out when your AC is running?
Watching this as my '16 has mystery water leak too. Sometimes water is filled in the second row seat bolt wells, the last time things got wet was underneath the right second row passenger seat only the carpet. Just a lowly XLT... No sunroof, heated/cooled seats etc. My '04 had a mystery leak on the driver's side near the A post recently, I checked and reglued the weather seal on the door frame and that seamed to stop it. On the '16 the water inside seems to only happen with a windstorm and rain so I suspect perhaps door seal s well but don't see any issues.

You commented the water was cold, I would review A/C drain lines. Not sure if there are two evaporator coils with dual air. possibility of rear A/C drain line
Was the water on top of the seat cushion? If it was, it must have leaked in from up high. Before ripping into anything, check the two front sunroof drains in the cassette by opening the sunroof and standing up inside the truck looking at the 11 and 1 o clock positions in the tub of the cassette. Look around to see if there is any debris anywhere in the cassette tub that could float around or be clogging the drain like leaves and pine needles. All sunroof seals from any car manufacturer leak water past the seals into this tub and down the drains. Sometimes debris in this tub can partially block the drain and depending on the angle the car is parked on, the water can overflow into the car. You can also pour water into this area to be sure it drains and runs out the bottom of the car and doesn’t drip into the interior. I didn’t have a chance to run out to my Expedition but the below is what to look for. The cassette has 4x in total but I’d focus on the fronts. Debris is the biggest problem and second is the drain behind the a-pillar is not pushed tightly onto the cassette tub drain but you would need to pull the a-pillar interior trim to get to that.
