Fog/Mist coming from ac vent. Air is cold. What is going on?

Update:

'97 Honda Accord. AC has not been serviced.

Thanks.

Update 2:

It occurs when the vent is opened and when it is closed.

Update 3:

I don't think there is a sweet smell or any smell to it. It's probably humidity.

Update 4:

There is condensation dripping underneath when the car is parked.

    If it happens only briefly, and there's no smell, it's just humidity condensing out of the air. Nothing to worry about.

    If it's continuous, and there's a sweet smell, it's antifreeze, coming from a leaking heater core. That's a problem that will leave you stranded by the side of the road with a fried engine before the summer is over.
