Water is getting into my 96 VR4 with an electric roof. My first suspicion was the roof, but so far, I have not been able to specifically locate a leak in it. I've poured a cup of water into the track area of the sun roof and it follows the drain in the back straight out the car. It pours out quick from the back, so there is no restriction in the plumbing. So far I have only tested this on the passengers side since that is where the water is collecting in my car. Specifically, the water is pooling in the back foot area for the rear passenger seat, and under the passenger front seat. The carpet in the front where the front passenger would rest their feet is completely dry.
So far, I have not seen any evidence of water getting in through the door, nor do I see water getting inside when I pour water in the sun roof. Where else might water be able to get in? My sun roof seal seems nice and supple. If I need to replace it thats fine, but I would expect if water is flooding into there, I would see water spots on the interior roof fabric. Other than a few dirt stains from oil on hands, the roof fabric is mark free.
On a side note, I have a suspicion this problem has been around since before I purchased the car in 2004, but the previous owner mitigated it by pulling one of the rubber bungs on the floor in the rear out to let the water escape. I just recently stole a bung from a parts car, and replaced the missing one on my car, and now have for the first time seen this water problem.
I'm not looking forward to the cleaning I'm going to need to do soon to this car since it is starting to smell of funk. On the bright side, I see no signs of rust, though I am not going to let this continue so that rust can find a way to take hold.
Help me figure this out and nip the problem in the bud.

BTW. there is no water under the rear seats themselves. Only on the floor just in front of them.
