Is the wet area specific to one side? You may also want to check the water deflectors interior to the rear doors if the door seals themselves check okay. When the water deflectors fail especially at bottom edge of door, water trickles in underneath the interior door panel, then under the carpet strip (threshold),then works its way under the carpet. It'* a very sneaky hard to find leak. As a quick check, remove the interior door panel, close the suspect door, walk around the car, open the opposite side door, lay on the bench seat, have a helper pour a quart of water right down on the window of the door you think is leaking. You'll see exactly where the water is entering.

it gets equally wet on both sides in the rear. Car is not being driven so anything that isn't from gravity wont work.

Water deflector failures result in just that, gravity leaks. Water naturally flows throught the doors. The water deflectors serve to keep water out of the passenger compartment and let it flow through the door out the drains.
