Hello, I have a 2013 Sonata Limted. It has the backup cam/touchscreen and the dual zone climate control system where you push on the head, body or feet of the stick figure to direct air. The problem, as I move toward my first winter of owning this, is that, as far as I can tell, I can not have the defroster going while also blowing warm air on my feet. As soon as I touch any body control the defroster clicks off. Nothing seems to indicate malfunction...is this just the way the 2013 Sonatas were designed ? This may be the only car in existence where you can defrost and blow warm air at your feet... Just trying to save a trip to the dealer if there is nothing wrong... Thanks, Steve
