THIS JUST STARTED. I HAVE NEW 2007 FORD FOCUS. THE HEATER BLJOWS AIR BUT COLD. THE CAR IS UNDER WARRENTY, I HATE THE IDEA OF SITTING IN A DEALER FOR SEVERAL HOURS. I WILL HAVE TO. BUT.... ANY IDEA WHAT IS CAUSING THIS?
AT FIRST IT WAS BLOWING HOT. THEN WHEN I WAS DRIVING ABOUT 20 MILES AND HOUR IT WOULD START BLOWING COLD. THEN WHEN I EXCELLERATE THE CAR IT WOULD BLOW WARM. NOW 2 DAYS LATER IT JUST BLOWS COLD. LIKE THE AIR CONDITIONER IS ON.
