Help, I can’t see anything anymore !!!

Hello, after it is very wet cold at the moment, my car does not manage to get the windows properly free any more. When I turn off the car and start it again after some time the windows fogged within a few seconds. A pressure on the disc de-icing button leaves the blower hurricane-like blower, but even the windshield is not free until after a few minutes. Even if I had switched on the heater in the morning before, the windows are at once I’ve already checked whether I might have moisture in the footroom, but I don’t know what to do. Aslo in damp weather and at outside temperatures between 0-5 degrees, the car is hardly mobile. Do you have the same problems, or do you know what else it might be?
