My door was running water through it as normal but in the end it was all down to a broken 'pop rivet' (the wee clips that push onto the metal holes on the door).The Clio has a ‘wet door’ system (as most cars do). The water runs down the window, between the window and door seal and makes its way out the bottom of the door. There is a membrane on the inside of the door card which, if damaged or detached, can let water enter the car. I’m guessing you haven’t had the door card off yet to check if he membrane is fixed as it should be? Also, have you checked the drain hole at the bottom of the door? It could be that something is blocking it causing the water to back up and enter the car that way.

The one above the speaker was snapped in half and turned out the water was somehow getting down the door as normal and slowly dripping through the broken clip and down into the carpet.
Was the worst experience I've ever had with any car and turned out to be something so stupid, just glad I found it! The weeks of constant trying to dry and the smell is soul destroying.
Definitely strip the door and check all the clips are intact and not broken. Also taking it off and putting it back on might correctly install some that may have not been properly popped in. When reinstalling just look where all the clips are and make sure you push hard on it.
Hope you get sorted!
