Hi there,
I own a 2017 6 sport, 50k mi, only one incident of collision damage while I was parked on a side street and it was all surface-level. I honestly can't remember when I started noticing this problem, but I don't recall it ever being as bad as it has been so far this winter. Essentially, the defrost fans are working at around 50-70% efficiency. I run them with the A/C on to reduce humidity, full heat, no circulation. The front windshield stays mostly defrosted, but about 2-3 inches running down both sides and across the top stay frozen, enough for my wipers to scrape against chunks of re-frozen ice that's been melted and blown back from the center of the glass. The front passenger windows only defrost about halfway back, and the rear passenger windows get completely frozen over to the point where I can't see out of them at all. This is obviously a major safety hazard. I have no idea what could be going wrong. Bad blower motor maybe?

Any advice would be appreciated. Thanks!
