From the rear passenger where you open the door looks dry but where the floor mat underneath is moistopen the rear hatch and look up at the weather seal along the top edge where the 3rd brake light is
sometimes the seal gets messed up/twisted and this can allow water in.
other sources can be from behind the outside plastic pillar cover, remove the cover and check the plastic fins, these allow air pressure out when you shut the doors but they can break off and this allows water in.
that's unusual, have you looked underneath the body there? any rusted out spots? holes drilled? have you lifted up the carpet there and inspected? I guess it's possible the door seal could be bad or the side glass seal on that side, you will probably have to inspect it a bit to figure it out, there are no inside causes unless it is coming from the front somehowThis is where it gets wet/ moist
The underneath looks fine but could it be from exhaust?that's unusual, have you looked underneath the body there? any rusted out spots? holes drilled? have you lifted up the carpet there and inspected?
