A lot of water has accumulated in the rear footwell of my car behind the driver's seat. I had someone suck out a lot of the water with a dry/wet vacc and I used a fan heater on the floor of car to dry as much out as possible. However the car is now soaking wet again and water sploshes under the carpet when I press on it! Rear light fitting has been checked and also inside the boot, door seals.....but none of these show a problem. Can anyone suggest what can be causing this water to flood into the car. I don't have a garage or carport, so car is exposed to the weather while standing on my drive. I'm getting desperate, as I am recently widowed and am worried about any damage being caused by all this water in my car.
