Misting? From under the hood or out of the vents? If it is out of the vents, that is normal when the humidity is very high. The air from the outside is full of moisture, when you cool it by passing it over the a'c coil, the excess moisture will appear as a fog briefly. If you put the control on recirculate, you use inside cabin air and that should stop the problem. All about relative humidity. Warmer air holds more moisture. For instance in the winter when the RH is maybe 30% outside at 30 degrees, you bring that air inside and warm it to 70, the RH drops significantly. Don;t have the formula off hand, but it whu you get the static electricity shocks in the colder weather.

Why does my kia picanto 2013 windscreen totally mist up and will only clear when i put ac on hwen it clears i turn ac off then within seconds it mists up again


the windscreen fog is from humid air coming in from the outside
air conditioners work by removing the humidity from the air so if you close of the outside vent then the recirculated air inside the cabin eventually has all the moisture removed
that is why the windscreen clears because there is no moist air to condense on the cold windscreen
now you will say that it is too cold and that is why you turn it off
well try this -- leave the ac on and adjust the heater control to produce lukewarm air no fogging up and not cold
it is called climate control

Air vent schematic


air for the inside of the car comes from the vent at the base of the windscreen or is recirculated inside the car
if you see what appears to be mist, fog or smoke from the ac vents ,it is extra cold air from the ac system that is seen as fog when it hits the air in the car
you will know exhaust fumes by the smell

Condensation of Interior of 54 Volkswagen Passat


Correct.
The ac runs in defrost mode to help dry the air blowing on the windshield. The cabin has too much moisture in the air.
You need fresh outside air and it needs to be dried by the ac to work correctly. So if the cabin air filter is dirty you would not get enough fresh air.

Heating AC problem


It sounds like the heater core is leaking engine coolant into the passengers side compartment. White mist could be steam from the hot coolant? The Heater fan could be damaged, or it is a short. Fill your radiator and take it to the shop or replace the heater core.

2001 Camry water on floor of rt side front and back, fog mist coming from ac vent, 90 degree weather, no rain. Back floor was pooling with water, no odor


Most likely the ac drain is stopped up. The drain is under the car near where a passenger feet would be. You can try gently running a pencil or something similiar to clear it out or compressed air.

Jeep '99 Mist from AC vents?


It would seem that your a/c is working very well. You most likely live in an area that is high in humidity. When the cold air from your a/c hits the moisture saturated air from the environment it turns the moisture to fog "condensation" . That is most likely your mist. Hope this helps. Good luck.
