Why is smoke coming out of my car’s vents?
When that happens, smoke is produced, which comes out through the AC vents. In case it is odorless, and more like icy fog, it is a sign that the coolant level is low. Either way, smoke coming out means that you need to check the coolant level in your car.
Why is there smoke coming out of my air conditioner?
When pressures in the A/C system arent proper, or the refrigerent is low, you get an evaporator that acts like a freezer. The ice builds inside the evaporator then starts to break off and exit through the vents. Thats the "smoke you see".
Why do my vents burn up so fast?
(Reese) maybe you have something stuck inside the vents or in the blower all those solinoides and wires and burn up stuff like leaves or could be just lint in the vents if their dirty. Car: I HAD a 1991 240sx coupe. woked NA motor. ran like 14.5 ish. blew it up @ 140 after an ECU reflash.

Why does my evaporator smell funny?
It probably smells funny because your vents, ducts, and the evaporator itself have funk in them (best way to describe it...basically, dead skin, cat hair, dandruff, pollen, etc.). 10 seconds was probably just enough time for a patch of ice to break free and be blown through the system.
What happens when the air passes through the evaporator?
What is happening is: As the air passes through your evaporator core (from the blower motor) it gets cooled by the evaporator . This cooling causes condensation on the evaporator. When pressures in the A/C system arent proper, or the refrigerent is low, you get an evaporator that acts like a freezer.
What does it mean when your car smokes?
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. Put it out and sell it to someone you don't like.
Where does electrical smoke come from?
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.
How to tell if AC blower is oil leaking?
Your next clue as to the source of your smoke involves the thickness or density of the smoke. A faint whiff and occasion al wisp of oil smoke with the AC blower on low will generally indicate a minor oil leak in the engine compartment.
What does burning oil smell like?
Most people know the scent of burning oil; it smells like an asphalt parking lot on a hot day, roofing tar or driving by a road-paving construction crew. Electrical wiring burns with an incredibly acrid, eye-watering stench.
Can you still sit in a car when you smoke?
The primary problem is probably that you're still sitting in the car instead of running for your life, or at least going for the nearest fire extinguisher. 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.
Does coolant make you want to jump out of the car?

What happens if you smoke a car exhaust?
Exhaust leak: If the engine itself or somewhere other than the tail pipe is smoking you could have a break in the exhaust line allowing the smoke from the exhaust to come out from the engine area or even the passenger area if under the car. Not too expensive, but fix it before it kills you dead.
Why does my car blow white smoke?
It is very unlikely that a clogged air filter would cause an engine to blow white smoke. Typically white smoke indicates that water (or coolant) is getting into the combustion chamber. This is symptomatic of a blown head gasket.
What does it mean when your engine smells like oil?
Oil and/or Coolant leak: If the oil/coolant leak drops either fluid on the engine from a small leak, you’ll get lots of smoke. Oil based smoke is usually blue and smells like oil. Coolant smoke is usually white like water vapor and has a sweet smell.
Why does my car smell like antifreeze?
There’s also a smell of antifreeze. It is very unlikely that a clogged air filter would cause an engine to blow white smoke. Typically white smoke indicates that water (or coolant) is getting into the combustion chamber. This is symptomatic of a blown head gasket.
Why does my engine have the same amount of air and fuel?
The engine is getting the exact same amount of air and fuel in both cases because you are traveling at 40 mph. the filter is designed to allow all the air necessary to make maximum power, at maximum RPM, at maximum load. Most peoples driving habits never come close to matching those conditions.
What does it mean when you have oil in your exhaust?
Oil in the exhaust means that the engine is already worn out and has to be either completely rebuilt or replaced. Water (coolant) in the exhaust gases can very quickly lead to extreme engine wear or catastrophic engine failure.
