Are there any coolant leaks in the vehicle? It sounds like the heater core may be leaking. Also, is the engine coolant full and clean?

There are no leaks that are visible, I do smell it and it seems the vents release smoke that seems to slightly fog the windshield from the inside. This smell is not very strong but you can smell it. Engine coolant is full..yes..

It sounds like the heater core is leaking. It could be a very small leak.
