Water in rear footwell

[EvertonSteve]

Hi,
I have a 2003 Convertible over here in the UK.
Recently, I've noticed the rear footwell (drivers side) is soaking. This was after heavy rain recently.
The roof has no leaks (fairly new).
The door seals are not perished and have no cracks, etc.
I have located the rear drain holes and cleaned them out. I tested these by pouting water down rear of roof and the water came through the drains to the front of the rear wheels.
Thought that would be it but, today, after more rain, the carpet is soaking again. Driving me mad!!
It's only the footwell floor.
Any advice would be greatly appreciated. Thanks in advance.

On my 03 convertible, I had water coming in the passenger side rear. There are drains back there that can only handle so much water. My floor would be soaked if I washed it and hit that area with a strong jet of water. Especially if it was parked front facing downhill. I learned not to do that.

Found a video on Modded Mustangs, but it won't let me link it with my phone.

Hi, many thanks.
I've just searched on Modded Mustangs and think I've found the videos you refer to. Definitely gives me a direction to investigate further. Many thanks for this....appreciated.
