Growingfamily

I test drove two 2016 TC Wagons one in Titanium trim and XLT trim. It's about 25 degrees out today. As we test drove the first car my daughter in the very rear complained of it being cold. After driving for 20 minutes the cabin finally heated up from the front console but the air from the floor vents in 2nd row and pillar vents still blew cold. The vents in the 3rd row also blew cold. I was wondering if anyone in this thread was able to find a solution on their own or provided one by the dealership. The wagon was everything we are looking for in a vehicle for our growing family but I can't have my kiddos freezing...
