I've got water under my passenger seat, I've unblocked driver and passenger rear drains which I'm hoping has solved the problem. Has anyone else had this issue and was it the rear drains that caused it?
Water on the passenger side can be getting in via the door card, the door seals or a blocked scuttle. If the roof motor drain holes get blocked water overflows and can find its way in behind the seats. I think this is what mine is suffering from but it is very difficult to unblock on the passenger side as the roof motor get in the way of a good rodding. I am going to get the roof motor noved into the boot this spring so hopefully I can then rod the holes properly.
You may want to check the other leak areas and when you say you have cleared them did you get a flow of water.

As above - Problem is most likely to be related to a damaged membrane in the passenger door. Remove the door card and check it is intact and fully sealed.
That would make sense as I've had the door cards off for a week while I've being doing sound deadening and stereo upgrade. I refitted it all now so hopefully it should be all sorted now. I might pop the cards off again and double check though just in case
