Why is steam coming out of my AC vents in my car?
Steam coming from the car’s A/C vents is typically nothing to worry about. “The odorless steam coming from the vent is possibly excess water accumulating in the heater box, which may indicate the drain hole is restricted and needing cleaned.” …
Why is mist coming out of my AC vents?
Fog or smoke coming out from the air vents on your air conditioner is caused by cold, dry air coming in contact with warm, moist air near the air conditioner. A dirty air filter or low fan speed may aggravate the condition.
What does it mean when your car air conditioner blows smoke?
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.
How do you fix condensation in AC vents?
Try to reduce the humidity level in the air near the air ducts. You can go for a dehumidifier if that helps to reduce the condensation. Unblock any ducts that are restricting airflow and have them cleaned regularly. Regularly clean your air filters and change them once every three months.
Why does my HVAC blow cold air and hot air?
Drivers changed air temperature far more often than they change the mode (defrost, floor heat, dash vents, etc.), so the temperature actuators generally fail first. When that happens, the HVAC system can be stuck on blows cold air or blows hot air. In a dual zone system, you wind up with a blows cold one side, hot on other side condition.
Why does smoke come out of my air conditioner vents?

How is hot air discharged from a steam vent?
This is different from the valve on balanced pressure type air vents, which opens at a temperature that is a certain number of degrees lower than the saturation temperature of steam. Hot air is therefore discharged at all times regardless of fluctuations in steam pressure.
Why does my car have no air in the vents?
Step 3 – A fan blower motor is controlled by either a switch in the passenger compartment or by a computer. If this fan motor is starting to fail it will cause the fan motor to run at a lower speed resulting in low air flow. To test this condition an amp meter is needed, connect the meter lead to the power wire of the fan motor.
