Defroster vents improperly positioned to keep front windshield clear in near zero conditions. Window wiper blades park in an area below the heated portion of the windshield. Wipers froze to the window, during the delay in the interrupted operation, while driving in a snow storm at 3 deg. Temp. Window actually became totally frozen over and visibility became impossible. On the passenger side, ice accumulated in the wiper pave in the lower right corner, about 3 x 6 x 1/4 thick and the wiper had to navigate up and over this frozen mass.
