Today I noticed a small pool of water on the passenger side floor. It was sitting on my floor matt. I then had a look around and I found the water to be sitting on the door seal, under the front passenger door card. It's been coming in and running onto the floor. I take it from the looks of it, it's been leaking behind the door card. If I remember right the door speaker was an issue on some peoples cars? What was the cure for this? The next trick is to see how the door card comes off, as I have never removed the door card on the Astra MK5 before. Thanks
