We got MS with rear child seats and love them. However , today, while we were driving, my son complained that he was too hot back there and I turned A/C all the way down and was pretty cold myself, but son said it was still hot. When I stopped the car, he was all sweaty and red and was almost passing out. I was wondering if there is way to cool the trunk more efficiently? I realize, that most of he heat is coming through the windshield , but is there a way to counteract that with better temperature distribution or something like that? I am dreading hot summers in Houston, that would be a nightmare if it's hot now. Anyone with the similar experience?
