Wanted to share this in case helps anyone else out there.
I had water leaking into the area behind the passenger seat when it would rain. I cleared the drains as recommended but it continued. I finally got fed up with it and poured some water in the drain area with a bowl underneath to see if everything poured in came out. Sure enough it didn't, but it also showed me exactly where it was going. There was a small rip in the lining around the drain that the water could seep through. If it did, it would soak in through the foam to the area behind the seat. A little silicon on the rip fixed it right up! Pictures are attached.
