That "mist" is more than likely coolant steam coming from a leaky heater core. Replacing the heater core is your best option.
Smoke could be coming from the vents of your car for a number of reasons. You may have an internal car fire.
Bad blend door, blockage in the duct system, or defective blower motor are all possibilities.
someone wetting themselves in the car because they couldn't get to a toilet quick enough
Coming out of the vents around 43 degrees
Hey Mike==If your car has A/C when it is exceptionally humid outside, it is common for the vents to blow some vapor. It is generally more visible when the sun is shining inside the car. Nothing wrong. GoodluckJoe
your blower motor is stuck on low
55 degrees above zero Fahrenheit
Smoke, Mist or Fog will come out of your A/C vents on hot, humid days. The reason for this normal phenomenom is the cold, dry air coming from your A/C vents is lower than the dewpoint of the interior cabin. Basically what this means is that cold, dry air is mixing with hot, humid air and causing the smoke. This is similar to when you open your freezer door and see the fog coming from the freezer. This is a normal condition and will eventually dissipate once the temperatures in the interior cabin and the A/C vents start to balance out. One way to quickly balance the temperature out is to keep the A/C system on recirculated intake air. Hope this answers your question.
It means to remove water droplets from something, typically a car window that gets mist on the inside. So the heater is used to remove the mist.
