I have a solid roof. I was told it was better for cold and hot weather in keeping the heat in during winter and not letting the heat in during summer. Winter passed and was fine, heat worked well enough. We're in the midst of a heat wave, and its weird. Sitting in the driver seat, i feel a heat draft coming from the back of the car. Im 6'0" so i sit very close to the ceiling of the car. When i touch the ceiling, i can feel that the front area is not hot, but the rear passenger ceiling area is on FIRE. has anyone else experienced this? Am i missing some insulation somewhere?
