How do you repair the center dash AC to blow air only the side vents blow out air you know that you need a mechanic but that is not funny?

Diagnosing this problem depends heavily on the year, make, and model of your vehicle. Some older cars use vacuum powered doors inside the vent to control airflow output location, so there maybe a vacuum leak to the center door. Almost all cars have handles on the vent outlet grill that manually directs airflow from side to side, and can completely block the vent if needed, so the center vents maybe be closed. Newer cars use temperature sensors, mounted under the dashboard and inside the vents that can control airflow, so the temp sensor maybe out of range. In vehicles that have sat for long periods of time, or are seldom used, rodents build nests inside the vents and block the airflow, so there maybe an animal nest in the vent. Without knowing the specifics of your car, my only advise can be to have a mechanic professionally diagnose your vehicle.

types of airflow, functions of airflow, properties of airflow,


Why would the ac and heater blow air through the defroster or the dashboard vents but not through the floor vents.?

It should blow through the floor vents. Modern vehicles generally use movable baffles in there HVAC systems, to direct air flow where the controls indicate. If the controls allow airflow to the floor, but nothing flows out, there is a malfunction between the control switch and the actuator that directs the flow.
