Foot well fills with water when it rains

[Guest]

This is really annoying me, i thought i'd found where the water was coming in but it's somewhere else. It only happens when it rains for a couple of days or it rains fairly hard and the foot well eventually has standing water in it. I've checked all of the drains by pouring water in them from the top and caught the same amount of water back from the exit tubes, there's 9 in total and they all work fine.

What i do know is, where the bonnet release catch and the boot switch release are located, the carpet is wet below them but not above, it's also slightly wet coming back from them towards the door and obviously it's really wet on the floor as this is where it all ends up. I've gotta get this fixed otherwise by the end of the long wet winter months, my car will only be fit for a fungus farm. Has anyone got any experience of how the drain by the bonnet hinge in the engine compartment works. Is there a pipe that runs from there or does it just drop down that cavity and run out of a hole in the bottom?

Check the drains in the heater air intake space (the space behind the bulkhead, and below the windscreen) this is prone to getting leaves and stuff in it, it fills up and comes through the heater vents. There should be two rubber bung type things in the bulkhead which should drain this area into the engine bay.

I've found out where the water is entering the car. It was below the boot release switch.

Underneath the switch there's a hole that takes the wiring loom somewhere else in the car. The water collects in here and then runs down into the foot well.

I dried everything off and then poured water down the windscreen so it uses the drain channel below the fuse box. I then checked inside this hole under the switch and it's wet again. Then i removed the interior light switch from the "A" post and it's wet inside and above this hole. So it's coming in from the drain in the engine compartment and into this box section and running down the inside of it where the hinge etc are bolted on. Now how to find out how the water gets in there....

Could it be anything to do with the fuse box or the hole underneath it?

My dad had this problem on his Volvo, it eneded up being the windscreen seals. It was to going down the side A post and coming through the hole exactly were yours it. my water problem is that my rear passanger foot well is filling up with water. I posted in the 944 section. If anyone knows whats causing this, please have a read.

I'm pretty sure the 968 has a bonded screen, and the trim is purely decorative. If it is coming in the windscreen edge, you have a bigger problem than just water, as the screen forms part of the structural integrity of the shell.

PS. Check that the drain tube from the front sun roof drain has not detached itself (though God knows how you'd get it back on!) This would mimic the effect of water coming in round the screen.
