Car ventilation works normally, except "defroster" and "defogger". Having blown in a windshield does not work. Snow on a windshield does not thaw in the winter. What reason can be?

Hello and thanks for the donation!

I'm not sure I completely understand the question. Are you saying that when the heater is set to the defrost position, it isn't blowing or it isn't warm enough to defrost the front windshield?

In various positions of the heater ventilation does not blow on a windshield, and also very poorly blows in feet, but always well blows in car salon.
