Just got a KIA Forte EX 2010 for my birthday this week and i cant seem to find how to turn off the ac. I push the ac button and the light turns off (which i would think that would turn it off) but as i keep driving i put my hand over the vents and there is air coming in, if my temperature knob is in the cold section (blue) cold air comes in even if the ac button is off, same for the heat. I always drive with the windows down so it is annoying to have either cold of hot air coming into the car..... Can Anybody help... THNX
