So far I am struggling with the wiper design now that winter has reared its ugly head in Canada. First of all I can't just lift the wipers if I know it will be icy and have to turn the car off when they are running so they are on the window and not at the bottom. Secondly, they seem to sit well below the part of the windshield where the defroster hits the glass. I had some frozen ice just about the wipers and despite putting the defroster on full blast for 20 minutes, the ice would not melt. I had to bang it with my hand to get it to eventually come loose. Seems to be a major design flaw for those of us in cold climates with lots of snow and ice.
