It will run until the high pressure safety switch (assuming you have one) trips it out or the compressor dies if you don`t have one. If you must run the ac, put a lawn sprinkler or a hose nozzle set at mist and aim it on the coil to keep it cool until the fan can be repaired.
If central air conditioner turns on but is not blowing through the vents, check the filter. If it is dirty, change it. Change the thermostat into cool, this will defrost the air conditioner.
When there is a problem in the vent system it defaults to defrost setting. Check the doors & vac supply
Check for a vacuum leak -sounds like it is starving for vacuum and reverts to the default position
2003 crown vic air conditioning vent dont blow
yes
No power, no air! Simple
Sounds like vents are in open position where it passes through based on speed with or without fan on
this one is easy your switch the controls the vents is not working there is a flap the closes the defrost vents so that it goes through the other vents or there is a vacumn line that is controlled by the switch, and its leaking. The vacumn line is usually on the engine side of the firewall. It is a very small plastic tube comming out of the middle of the firewall at the top and it connects to a junction with other vacumn lines. See if any of them are disconnected.
Doors in the kick panels or heater box are not closing to redirect the air.
Jammed blend door or blockage in the ducts if you mean to say air isn't blowing through at all.
