I know this is the lightning area but I need a clue where to start, my 01 ford expedition's ac smells like antifreeze. U can see some little traces of smoke coming thru the ac vents and it smells just like antifreeze. Can someone give me an idea of where to start to find out why it smells like this. I have noticed a small spot on the driveway at times underneath the right side o the truck by where the starter is

Bad heater core.

I kinda thought that but it was throwing me off because it was doing it with the ac on and not the heater

coolant still flows through the core, regardless if your temp is set to hotter or colder. it's really just a door flap that moves between the evaporator and the heater core.
