this was happening on my s14 lad you might have a different problem but mine was leaking water in and around th back driver side light and filling the pocket with water and it was travelling up under the back seats and lodging in my drivers footwell, only figured this out when i took out the interior. worth a look....

had this problem on my first booted cam scamp . now i figured it out in a few hours . but what you will have to do is check all the pannel joints in and around the are its coming in you think . and any joint or even where the bonnet hinge's are tiger seal them up and i dont mean smather them in it either . but check the likes of the wheel arch and around the bottom of the piller and so on for the small gaps that might be letting it in . on the cam that time it was coming in around the door hinges . and i know you might not like the sound of it but if you do find the leak and fix it theirs no harm in drilling a small hole where the water gathers under the carpet so your not dragging a swimming pool around with ya
