Whenever it rains, the carpet on only the drivers side gets wet. It is not flooding though. The carpet is wet on top and the bottom of the carpet, which is plastic, have all this water drops like moist on it. I couldn't find any leaks from windows, moonroof, or the door. All other parts inside the car is dry, only the carpet on driver's side is wet. I'm can't find the problem. Any ideas?
Edit: It doesn't happen when I wash the car, only when it rains a lot.
The car is 2000.
