The temperature dropped, in the Chicago area, below 20 degrees F for the first time this winter and the windshield wipers on my 850 have started the same old routine of only partially clearing the windshield.

When it gets below 20 degrees F, the position of the windshield wipers at rest, and the capabilities of the defroster conspire to allow ice to cake-up on the wiper blades, lifting them from the windshield and preventing them from doing their job.

My washer fluid is antifreeze-based.

Do any of you Canadians have a solution to this problem?

Was there ever an option for electrically heated wipers?

Is it possible that, when I've removed the lower windshield shroud, in order to do miscellaneous work, that, when I re-bolted the windshield wipers, that they are aligned too low and thus are not being heated properly by the defroster? Basically, when I have re-bolted the windshield wipers, I have put them in a position so that they are, at rest, as low as possible on the windshield surface.

Thanks.
