what to do: slices fogged like ass! sight = 0 [punto]

hello! have the pleasure in the early days with a fiat punto_s to drive to school to _dürfen_^^. problem with it is that at the moment is so damned stunned that I see almost nothing more. all the windows are closed, only the front window remains free for max 20cm from the blower! infos: -the car stands over night in an empty, normal garage – there are 2 people who are usually dressed thick – no matter if I heat on warm or cold, on 1 or 3, in which direction also stell I, I can’t do anything… what’s wrong, or what can I do? Is that what you guys say?
