No rain recently, used the hair dryer several times on floor mat. Get into car, floor mat is barely damp, drive 10 km and floor mat almost directly below brake pedal has a wet spot. Checked drain holes for front wheels, they are clear, no water in any other part of car including trunk. Driving on dry roads and yet wet spot shows. Dry it again and drive on dry roads and even as little as 5 km, wet spot is back. Anybody got any ideas.
