I can feel cool air on vented seats / on low setting / for my 13 Elite.
Now.. its hot [well for this old Canuck anyways..LOL] and I am wearing VERY light clothing.
but, if i were wearing a new pair of jeans... well the outcome/observation would probably be different.
I had a 2014 Jeep Grand Cherokee and the ventilated seats were VERY noticeable even on low. Unfortunately, I can hardly feel anything on HIGH setting in my 17 Advance. I can feel nothing at the lower settings. The "nature of the beast", I guess.
Well, I have found a much bigger difference than in my friend's from DSRLeasing Mustang GT 2017. It was barely noticeable there, but I guess this may be some issue and I advised him to go check it out.
