This should be a simple question to answer. We got lots of snow yesterday and, of course, the car was covered with snow and the area below the wipers was filled with frozen slush that would not come out. It is my understanding from discussions regarding A/C smell that this is where the intake is for the climate control system. My question is then, if that area is filled with snow and ice (hard to remove) where does the defrost air come from? It was hard enough to get the wipers free.
