Wet footwell

[Genty]

Hi guys I sorry bring up another water leak thread again. But I'm stuck ive tried and tried get to the bottom of this with no luck, my cars letting water in it only seems be getting wet on the passenger rear footwell ive re sealed the rear door to stop that with no luck ive checked the drivers door that's not leaking. The drivers footwell is only wet from the water being thrown up from behind I think cos Ive had my hand all up behind the glove box and at the back of the carpets and its bone dry? I'm stuck ive had the battery drains all cleaned and flushed a year ago so touch wood it's not that just hoping you guys can help now
