My 1999, 166 has developed a water problem. Whenever it rains i notice that the carpet under the drivers feet (left side) gets somewhat wet and the carpet under the rear passenger feet (left side) gets soaking wet. I only started to notice this problem last winter but this winter with all the rain that we have been getting in sweden its become a major problem. Where could this water be coming from? I dont notice anything around the doors and the underside was treated in 2003 so i dont think the water is coming up from under the car, but i cant be sure. So please HELP me and give me your ideas and thoughts as to where i should start looking to find where the water is coming from and how i can fix the problem. THANKS ALL.
