The air is probably too cold causing condensation at the vents. try increasing the air flow which will warm it a few degrees.
The thermostat tells the air conditioner to pull in air. The air then goes through cooling lines in to the house. goes through the vents and out through the registers in the rooms of the house.
Check for the drain hose or pipe in your unit so that it is not clogged. Through the ac process water is collected and thus needs to come out. If the drain is clogged water will be trapped and the blower will pick it up and send it through the 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.
Routine air vent cleaning saves homeowners money by improving the flow of air through the vent. When vents get clogged, the air has a harder time pushing through the vents, which causes energy bills to rise.

In HVAC systems, the air typically flows from the supply vents to the return vents.

If you are sure the blower is working and pushing good air flow, it could be the air flap that changes the flow from defrost to the floor or to the vents is stuck. It may be partly open but not all the way and only allowing limited air flow.
Weak air flow from the vents in your house could be caused by a clogged air filter, blocked ducts, a malfunctioning blower motor, or issues with the HVAC system. Regular maintenance and cleaning can help improve air flow.
I'm not sure what vents you are talking about, but usually air vents are known to be working if there is air flowing through them.
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.
