Possible condensation coming from tailgate window seal?
It rained very hard today. When I went out to drive, all the windows were fogged up on the inside. I've noticed on the rear window that some of the rubber seal is loose. I go to a carwash that has compressed air hoses to blow dry the car. The seal moves around when air is blown on it.
So, is the seal something that can be fixed without removing the glass. Or am I going to have to have a new piece of glass installed with a new seal?

This is what I'm talking about, mainly in the lower right side the rub er seal is coming out...

Just 'spitballing' here, so bear with me.
Have you taken off the plastic storage/access panel inside the liftgate and/or looked in cargo area under the tray for signs of moisture intrusion from that rear glass or sunroof drains, etc? Or raised the hatch and a bunch of water came spilling out? Otherwise, and especially after that ' really hard rain' you got, I'd be thinking about the typical water intrusion offenders on this car if it rained frogs for a good bit; primarily the plenum backing up with water as that's where the HVAC intake is located, etc., if you don't find any water in rear of car or in footwells. It may be too late to tell now, but an easy check is to pull out the cabin filter and see if it is holding water, stained, or has deposits/discolorations on the 'clean' side of the filter or it's housing, etc. It also doesn't require a lot of moisture to fog the interior windows up under the right conditions, and the air intake isn't sealed off unless the car is in 'recirculate' mode, so it's just possible the moisture intrusion was completely unavoidable due to atmospheric conditions.
I do keep a desiccant bag in my car to capture moisture and help prevent the interior from corroding and the protect the stereo amp and all the other electrical bits, etc. In fact it's time to change that out again; thanks for the reminder.
Word to the wise: Never put a desiccant bag/moisture capture device where it can do harm if it leaks, and don't leave replacing/servicing them to the point of bursting at the seams, or they probably will end up leaking, and you don't want that. Had one leak in cargo bay when it sat at a dealer for 3 months waiting on an EGR Cooler; thank goodness for the plastic rear cargo area liner...which, sadly, they failed to clean off fully.

I have yet to remove my broken Bose amp. But I'm beginning to think water may be the culprit. Since I have seen/felt water in that area of the hatch.
I plan on removing the amp tomorrow, so I will update if I find water inside that right hatch panel area.
If I do, how do I stop it from happening again? I don't want to spend $450 to fix the amp, only for water to damage it again.

Is this what you have in your Q and/or similar?
https://a.co/d/hdP57On
Where did you place/hang it?
Shame we have to resort to these measures, but whatever prolongs the vehicle's life I guess...

Sounds like the window seal is a likely culprit here. I'd call around to a few glass shops to let them know your concern and see if they can set it straight. Just spitballing as well, but I'd estimate the job at about $300.

Am I missing something here? Why not a bead of black caulk?

Well, hey, that's a place to start. @bg_2007Q7 likes to have his car sparkle, so a Wes-style repair just didn't seem like the right suggestion to me. Hahah!
