Wet carpet

[martmart]

Hello, I've got wet carpet in the front of the footwells on both sides of the car.

I've checked the drain holes next to the battery, under the roof and also at the bottom of the doors but cannot see any problems.

The only things I suspect is:

The wind screen seals - can these be checked some how as at the bottom of the glass on both sides it has delaminated

The aircon drain plug blocked - it does make a groaning noise when the ac is on! However, I'm not sure that it could be this as the carpets are wet when it been raining a lot.

Thanks.
