The AC is dripping water outside because it is removing humidity from the air inside the house and expelling it outside as condensation.
It is called condensation.
Either you can have a leak from the internal venting system that is causing this or you have a leaking heater core instead.............
most likely is the condensation from the AC, completely normal
That would be condensation from the ac system, this is normal.
The only water that should be dripping out in that general area would be condensation from the AC running.
Condensation forms on AC ceiling vents when warm air from the room comes into contact with the cold surface of the vent. This temperature difference causes the moisture in the air to condense and accumulate on the vent, similar to how dew forms on grass in the morning. It's a sign that the AC system may need inspection or maintenance to ensure proper operation.
No, the freon is in a sealed piping system. The water dripping outside is most likely due to condensation. Plus, freon is a gas under normal atmospheric conditions.
Look under the front passenger side floor pan near the transition to the firewall. Should be able to see condensation dripping if AC has been used.
Return air vents.........
yes
AC VENTS are in the correct position if they are open and free flowing. Some systems have a heat and an AC position for the vents. The AC position is so the cool air discharges from the vents higher on the walls or from the dash rather than floor or windshield in a car.
