low on coolant, dash control, blend door actuator are places to start
Check Antifreeze level..make sure there are no leaks under the vehicle.
It doesn't really blow it out it just warms the cold air.
Either a faulty thermostat or you have a low coolant level.
Our car had this problem. Answer was a new A/C computer needed.
Test the coolant freeze point to be sure the coolant is not freezing up when it is cold outside.
No! Thermostat.
Check the colant level, it may be low.
air conditorner doesnt blow cold air has freeon compressor doesnt kick on
you would need to add freon
Could be a bad thermostat.
One of the reasons a 2000 Jeep Cherokee heater would randomly blow cold air and then hot air and then cold might be that there is a problem with the hot/cold duct. The air or a vent might be inadvertently blowing periodically.
It might need to have the Freon re-charged.
