Just has this leaking problem with all the rain we had, front seatbelt was wet, water dripping from rear air vent above side door drivers side onto the step. Took it to my favourite Indy garage, he took off the trim around the drivers door and the drivers side sliding door, exposing the drain tubes, he said that the tubes are quite narrow for what they are so it does not take much to bung them up, they had black crud in them, he blew them through with an air line and washed them out, checked the other side, put it back together, just waiting for some rain now βοΈ
