I like my Fiesta ST a lot but there is one thing that I can not stand about it. Anytime I turn the HVAC systems from off to Auto, the system blows outside air through the dash vents at full fan speed. So if it is -15 out, I get a nice 15 second blast of ice cold air in the face. My dealer is saying they checked with Ford and this is normal behavior. I am not satisfied with that answer and am wondering if other peoples Fiestas are doing the same thing? I can recreate the issue every time I turn the system to off....leave off for at least 20-30 seconds so the blower door can move to its off position...turn to Auto and feel the blast of air out of the dash vents for 10-15 seconds.
