The most common cause for the defrost not properly working is a malfunctioning blending door. The blending door might be stuck halfway open. This would cause the defrost not to work unless the fan is on high.
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.

In your 1997 mustang the air is blowing through the defrost Why isn't it blowing through vents?
this one is easy your switch the controls the vents is not working there is a flap the closes the defrost vents so that it goes through the other vents or there is a vacumn line that is controlled by the switch, and its leaking. The vacumn line is usually on the engine side of the firewall. It is a very small plastic tube comming out of the middle of the firewall at the top and it connects to a junction with other vacumn lines. See if any of them are disconnected.

Why are only half of the defrost vents working on a 2007 freightliner Columbia?
If only half of the defrost vents are working on a 2007 Freightliner Columbia, it could be due to a few potential issues. One possibility is a malfunctioning blend door actuator, which controls airflow between different vents. Additionally, there could be a blockage in the ductwork or a problem with the HVAC control system. Lastly, low coolant levels or a failing heater core can also affect defrost performance.
