I have a 1999 Mustang V6 and have a problem with the heater. When I turn on the car and try to turn on the heater it won't come on it blows cold air, however, it does come on after driving for 15 to 20 minutes, and after I drive an overpass. Does anyone have any idea what maybe causing this and how I can fix it?
