I checked out a 2016 Edge Sport that had the heated/cooled seats. The driver's seat bottom felt cold but nothing happening on the seat back. I asked the salesperson if they are meant to cool the back or not and was told they are not designed to cool the back portion just the bottom.
FYI, my GF's 2016 Jeep Cherokee has cooled seats and the bottoms cool and just the lumbar portion on the back.
