I just tried this on my 15 PF when I turn the AC on cold air blows hard out of the rear center console vents as well as the 3rd row vents on each side. As I turn the temp up to get heat in the PF the rear center console vents have barely a trickle of air coming from them and no air whatsoever coming out of the 3rd row vents. With 2 small children sitting in the back I want to make sure there is plenty of heat coming out of the rear vents. Anybody get any results from a dealer on this??
