Over the last week or two i have noticed that the carpet in the drivers footwell and the matt are wet, sometimes very wet depending on how bad it has rained.

At first i thought it was a hole in the floor under the carpet, but it was suggested to me today it could actually be coming in through the door/window.

Im not really sure what to do?

Any ideas what it is lads and how to slove it?

Thanks
