Well now that the weather is warming up and ice is melting, i took the carpet out of my car and must have rung out and sucked out 10liters of water or more. Then i took the ceiling out and noticed the drain hose wasn't connected at on the passenger side and the drivers side was leaking a bit. I replaced the clamps and now no leaks that i saw. There are also 2 drains in the back of the car that i didn't know were there.
Anyway, I hope i got it all fixed now.
