I just got a new 2018 Edge on Saturday and love it but one odd thing just started happening today. When I crank up the seat cooling to max you can really hear the fan whirring. I swear I had the seat cooling on high before today and never remember hearing anything.
I don't know how it's related but the night before I did upgrade my Sync from 2.3 to 3.0. Anybody else have loud ventilated seats?
