While traveling from Fla with the A/C on, a mist came from the dashboard vents that had an anti-freeze smell. Prime Ford diagnosed the problem as the Heater Core. This weekend on a 200 mile trip, I ran the A/C and it was fine. Is this something that just happens occassionally until the Heater Core goes or could it be something else?
