Bill Allen, owner of Mechanics Plus in Casselberry, Florida, says that air flows through a heater core and an evaporator core before exiting the vents. If there’s a small pinhole — which is a small leak typically caused by corrosion — in the heater core, drivers may have steam coming from the vents , but it will likely smell of coolant.

U can also smell exhaust smoke in traffic. You air vent is not closing properly and too much of outside air is mixing with your cold air , or your aircon coil is really dirty and lots of water condensation in you aircon system. 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. If the air temperature near the unit is below the dew point, this causes water vapor to form in the air and condense into water droplets, thus causing the fog or smoke.

Why is smoke coming from the air conditioner vent when the heat is on while the car has been running for a while? If it smells sweet ,it is coolant, and the heater core has failed.

Oil leaking problems cause burning smell from car It’s a common phenomenon while driving uphill when you have to rev the engine more. AC blows what looks like white smoke Recently, when turning on the AC, it appears that white smoke is blowing out of the vents. It does not smell like smoke or fill the interior up with this cloudy substance. I'm guessing this is humid air arising from a clogged line, bad blower or something else. The AC still gets cold.

There are a few possible causes for this though. It is not coming from outside the car or the cabin air filter would stop it. Now the white dust could be aluminum oxide, or aluminum rust, as the fins break down.
