Antifreeze smelling white smoke or fog coming from the vents means you have a leak in the heater core or one of the connections to it. This will only get worse and needs to be repaired before you loose all your coolant. If it smells like burning leaves or grass then it is possible that leaves have found their way into the heater box. A lot of vehicles use a resistor block that is mounted in the heater box to provide resistance for the various blower speeds. When the blower fan is on low speed - then one of these resistors is in series with the blower. The resistor will become quite hot ( normal ) and since it is mounted in the heater box, the air flow will cool it. However if leaves or other foriegn material has found its way into the heater box - these can burn if they come in contact with the resistors. Usually it will happen once and the problem goes away. If it smells like plastic burning - then you may have a wiring issue.

Why is my house air running but no air coming from vents?
If your house's air system is running but no air is coming from the vents, it could be due to a few issues. Common causes include a clogged air filter, which restricts airflow, or closed or blocked vents. Additionally, there may be a problem with the ductwork, such as leaks or blockages, or an issue with the blower motor in the HVAC system. It's advisable to check these aspects or consult a professional for a thorough inspection.
There is not enough air coming out the vents?
If there isn't enough air coming out of the vents, it could be due to a clogged air filter, which restricts airflow. Additionally, issues with the ductwork, such as blockages or leaks, can also impede air distribution. It's advisable to check the air filter first and replace it if it’s dirty. If the problem persists, consider having a professional inspect your HVAC system for any underlying issues.
What causes air not to come through your vents?
Air not coming through your vents can be caused by several issues, including a clogged air filter, which restricts airflow, or blocked ductwork due to debris or obstructions. Another possibility is a malfunctioning blower motor or issues with the HVAC system itself, such as a broken fan or thermostat problems. Additionally, closed or sealed vents can prevent air from circulating effectively. Regular maintenance can help prevent these issues.
Is it better to have vents in the ceiling or in the floor?
Does not matter. Air will displace naturally when pushed into a room from the vent. Vents and ducting are laid out according to the plans of the unit. That is the only reason for top vents and bottom vents. If you are speaking of the intakes, the same principal applies.

Why does air blow through vents on the dash but not through the defrost vents on top when you switch the control?
When you switch the control to direct air through the dash vents, the HVAC system redirects airflow away from the defrost vents. The system uses a series of blend doors to control airflow direction, and if the defrost setting is not activated, those doors remain closed, preventing air from flowing through the defrost vents. Therefore, air is channeled exclusively to the dash vents instead.

Why is there no air coming out of vents can hear air blowing under dash board?
The year, make and model would help but many vehicles use vacuum to operate the direction of air flow through the floor vents, dash vents and defrost vents. If the vacuum supply is cut off for whatever reason the system defaults to defrost only. So if you only have the defrost mode working chances are the vacuum supply is cut off. Check the HVAC vacuum supply line under the hood for damage. If that system seems to be working but you have insufficient air flow through all of the vents, check/replace the cabin filter if applicable.
