Hello! The floor on the back drivers side of my 2001 Astra is absolutely soaking wet. It happened one day that my car was flooded with water in the back of the driver seat aswell in the front to the pedals First the amount of water was big enough but after the sponge from the back of the pasanger seat and the floor sponge that is underneath got soaked with water. Its imposible for me to sqweeze the water from the sponge. Now its not leaking from nowhere its just the water that remained in the sponge. My question is how is that possible to find myself flooded with water only in the back and front of passager seat. Its seems that all water came from the back of the driver seat on the floor. What should I espect next that is going to happen? Is this going to damage my car in the near future?

Do you
have the same problem?

Some of what you're describing I'm having a hard time understanding, but to start with, there's two common things, other than leaking window seals, to look for. The first is if you have a sun roof, there are four drain tubes with hoses running to the bottom of the car. If one is plugged or blocked with debris, you'd think water would flow through the others, but if the car is leaning just a little, the water will spill over into the car before it gets high enough to reach those other hoses. The clue is something around the sun roof will be wet.

The second thing to look at is if a repair was done inside any door, there's a plastic sheet glued to it to keep water from getting inside the car. When it's removed, it is usually stuck on so tightly that it stretches, then when it gets put back in place, gaps form that can let water leak inside the car. To identify this as the cause, leave the doors open a couple of inches and place masking tape along the top gap to keep rain out. If the car still fills up with water, it's not a door issue. Look for water running down the inside of the firewall or behind the back seat.

Also look at the fresh air intake in front of the windshield or under the hood. If that fills with leaves and the drain hole gets blocked, water can build up high enough to run inside through the heater box. I've never run into this myself, but I've read about it a couple of times.
