Hey there, just got a used 2014 6 GT. It's winter now in Chicago and i've been noticing that the heat for the floor vents doesn't work well at all. I"ll get more heat coming out of the 'face' vents when it's on Floor than actually on my feet. Is this a common issue? I've had a Protege adn a couple 3's previously and never had an issue w/ the floor heaters in the winter.
