That is probably antifreeze steam. Your heater core is a small radiator used to heat your car. The engine heats the antifreeze and circulates it through the heater core. Your blower blows heat through the core (radiator) into the car, and warms you. If the core gets a small leak, it will put out steam.
replace the heater core
heater core
Could be an incorrect refrigerant charge in a/c system
heater core is shot and you have to get a new one
white smoke is coming from my exhaust why?
Head gasket more than likely! White smoke is coolant.
this kind of thing happens in my durango when i have the ac on and its humid inside the car.
White smoke coming out of the heater vents in a 2003 Honda Accord could indicate a coolant leak, possibly due to a blown head gasket or a cracked engine block. When coolant enters the combustion chamber or the heating system, it vaporizes and produces white smoke. Another potential cause could be condensation build-up, especially in cold weather, but persistent white smoke usually suggests a more serious issue requiring immediate attention. It's advisable to have the vehicle inspected by a mechanic to diagnose and address the problem.
White smoke coming from the air vents when you turn off the cooling effect of your car's AC system is typically caused by condensation build-up within the system. When you turn off the AC, the cold air stops flowing through the vents, causing the moisture in the system to evaporate and be released as white smoke. This is a normal occurrence and is not usually a cause for concern. However, if the smoke persists or is accompanied by unusual odors or sounds, it may indicate a problem with the AC system that requires further inspection by a professional mechanic.
it would cause overheating but the smoke is probally coming from some sort of water or antifreeze in combustion chamber
they have elected a pope? in cold weather it is normal to see white smoke coming out of your tailpipe. the one you have to worry about is the black or the blue smoke
A fine mist coming from the air system is engine coolant. The most common cause is a leaking heater core.
