I was giving the car a thorough clean at the weekend and took off the plastic trim that covers the join between the carpet and the bottom of the rear door opening on the drivers side, it's the section that when removed you can see the wiring loom. There was a little bit of clear water in there and I soaked it up with a piece of kitchen roll, I should say that I park the car on my drive which has a slope on it so the nose of the car is up. Do any of you know where the water may be coming from and how to fix the leak, as I want to get my headlining done and there's no point if it has rainwater coming in.
