Does my AC have a fresh air intake?
The indoor portion of your unit has an air conditioner return air intake, usually located on the ceiling. This return air intake grille typically includes some type of filter to keep dust and debris out, while allowing air to pass through. It will be exactly the same, if not a little cleaner thanks to the AC filter.
Why does smoke come out of my air conditioner vents?
Fog or smoke coming out the air vents is caused by cold dry air coming in contact with warmer, more moist air near the air conditioner.
When does smoke come in through the ventilation?
A visible stream of constant smoke tells you that the source is very near the blower or the air intake, or is inside the duct itself. If smoke billows out enough to visibly fill the cabin, then your car’s probably on fire.
Why does my AC blow smoke in my face?
If you only smell electrical insulation with the air on recycle, you likely have a wire shorting behind the dashboard. If you’ve got an odorless “smoke” that only happens with the AC on high, then congratulations — you’ve got an AC system that blows cold enough to condense humidity into vapor and blow it in your face.
Where does the smoke come from in an engine?
This is a particularly useful trick for locating coolant leaks, and figuring out if the smell is coming from your engine bay or heater core. Electrical smoke drawn in through the fresh air vent is probably coming from the engine compartment, perhaps as a result of a wire touching something hot like the exhaust manifold.

What kind of smoke comes out of vents?
Suddenly, what appeared to be whitish smoke started coming out of the 2 center vents. I quickly turned off the air conditioning, and the smoke stopped coming out. After around 10 seconds, I turned the air conditioning back on and no smoke came out. I drove for another 30 minutes and didn’t see any smoke again.
What to do when smoke comes in through the ventilation system?
But all jokes aside, a bit of smoke coming through the ventilation system need not necessarily spell doom for you or your car — it all depends on what’s smoking and where it’s coming from. The first thing you’ll need to do is identify the type of smoke, and the best way to do that is by smell.
