I see a misty smell like anti freeze coming through the vents in the car

Holy cow you can see smells?????

haha just messing. If you have the smell of anti freeze coming through the vents it means that the heater core needs to be replaced. The heater core cycles the hot engine coolant and uses that to warm the air to give you hot air. If you can smell it it is leaking into the vent system and needs to be replaced.

Heater blows cold air

Check or replace the thermosata. But first make sure you have anti freeze and oil.. They work together in giving heat.

Good chance that it's in the wheel well. Do some research and make sure there's no text service bulletins on the vehicle.
