Wet slices in moose

Hej together, our 1995’s 850-second wheel is for a few days in the rain an evil wet biotope, on all the windows? Great deal with the windshield and the side windows in front. But even in the rear, the glazing is permanently humid. From the ventilation, comes also on maximum set very little airflow and the ventilation that comes there is damp warm. I can not wipe as fast as directly again everything is strongly fogged. Only a narrow strip, about the first 5-10 centimetres of the windshield above the ventilation grid, remains dry. It is not wet, it is wet and yes, it smells even when I use the ventilation instead. Driving in the rain is so impossible, except that all windows are completely open. What else is striking is that in frost above the dashboard parts of the windshield is light and from the inside lightly iced. And when the ventilation is busy, “twishing” something. Is that the engine/the wave from the indoor fan is completely open?
