Because there is a transfer of heat through the evaporator coils inside the conditioned air box inside the vehicle, there is a tendency to create condensation on the coils. This condensation is usually channeled off to the out side of the car via a drain path or hose. If the drain path is blocked, the moisture could build up inside the conditioned air box and leak. Also if a drain hose has been disconnected, this could also lead to a leak inside the vehicle. BTW, I have also seen interior fluid (radiator) leaks from the heater coil due to failed coil assy.
Go to a qualified automotive air conditioning technician. == ==
Probably low on freon, you may have a leak in the system.
The 1939 Packard was the first car with a true air-conditioning system.
Air conditioning.
The air comes from the air outside and the air conditioning system in the car turns this into cold or warm air.
I would say that it depends on the size of the freon leak, could be less, could be more.
HVAC in a car is the Heating, Ventilation and Air Conditioning system.
Part of Air conditioning system
There is a conditioning system drain hose. Eventually it starts to leak inside of the car. Fix the hose.
NO! You would never put propane in an air conditioning system! For air conditioning to work it needs FREON. Depending on your car you need to find out what kind of freon it requires, as well.
System is low on refrigerant.
No, it's part of the air conditioning system.
