How do you troubleshoot a heater ac that will not blow anywhere but defrost in a 92 lebaron?
There is a caseunder the dash that holds the heater core and ac evaporator core. In that case there are what are called blend doors. They are controlled by vacuum from the engine that runs to the doors through a diaphragm. The defrost/floor position is the default position that the blend doors automatically go to if there is a malfunction. Usually when that happens it is caused loss of vacuum. Another sign of a vacuum problem is when there is an apparent loss of air from the dash/side vent position upon acceleration which returns to normal when not accelerating. Annoying but harmless.
Why won't air come through the vents?
Does air come out at defrost vents? Defrost is the default position. Check for a vacuum leak either under the hood or under the dash Check the operation of the vacuum actuated motors under the dash Check the operation of the selector switch
What causes the air conditioner on a 2003 Chevy trailblazer to stop blowing through the ac vents and start blowing through floor and defrost vents?

How to tell a candidate they were not selected for the position?
When informing a candidate they were not selected for a position, it is important to be honest, respectful, and provide constructive feedback if possible. You can do this through a polite email or phone call, thanking them for their interest and time spent on the application process. It is also helpful to offer to keep their resume on file for future opportunities.
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.
What is the cause of the ac only blows through the defrost vents on a 2001 ford explorer track?
If the AC in a 2001 Ford Explorer only blows through the defrost vents, it is likely due to a malfunction in the blend door actuator or a vacuum leak in the HVAC system. The blend door actuator controls the direction of airflow, and if it fails, it may default to the defrost position. Additionally, a vacuum leak can affect the operation of the mode doors, leading to improper airflow. Checking the actuator and vacuum lines should help identify the issue.
Why does AC and heater blow air through defrost vents and will not blow air?
depending on what year and make it is, the most likely issue is that you have a valve that moves to divert air to the upper vents, floor vents, and defrost vents and it is either stuck in the defrost position, is broken, or a cable/connector has come loose. The valve is usually in the center of your dashboard up against the firewall. The air flow direction in many vehicles is operated by vacuum controlled servos. If the vacuum supply is cut off, the system reverts to it's default position which is the defrost mode. My guess would be that the HVAC vacuum supply line under the hood is disconnected, pinched or collapsed.
What is wrong when the air conditioner on a 1989 Oldsmobile 98 regency blows out the top and not through the vents?
Could be a vacuum problem--either broken or disconnected hose or bad vacuum motor under dash or coming in through firewall Defrost is the default position for this system

What causes the front air conditioner on 1999 Lincoln navigator to stop blowing through the ac vents and start blowing through the defrost vents?
When there is a problem in the vent system it defaults to defrost setting. Check the doors & vac supply
The air conditioner only blows through the floor and defrost vents on a 2003 Saturn L300 how do you fix this?
Many HVAC systems operate with vacuum supplied from the engine. If the vacuum supply is cut off the system goes into default position which is floor and defrost. Look under the hood for a small vacuum line from the engine leading into the firewall that is damaged, cracked, pinched or disconnected.
