If its been recently charged there maybe moisture in the system.
As the Freon level in your air conditioning system gets lower the cold air will become warmer and warmer. You will need to recharge the system with Freon.
Could be many reasons but the most common would be low on freon due to a leak in the system.
low freon or none
A short in the wiring.
If it stops blowing cold air then your clutch on the compressor is probably not any good, or it could be that you need to recharge your freon and lubricant
maybe the a/c needs to be recharged with freon
possibilities include thermostat stuck open (temp gauge would be reading cold), low coolant level, blockage in heater core, or temp door in dash broken(very likely on this vehicle)
I am working on my daughters but the first thing would be low on freon. Recharge it with a kit from AutoZone or similar store and ask them where the low side cap is. Read the directions on the can and just do it. If it takes freon, the can will get very cold and form frost.
Freon under pressure, much like LP and butane are liquid. At sea level pressure, freon becomes a gas. For freon to work in a refrigeration system, it must be able to transform from liquid to gas to liquid. So, to fill a system, it must be put into that system in liquid form. To do this, the bottle containing freon must be tipped, otherwise only freon the gas would be expelled.
Would depend on ambient temperature and freon level in system
You're not getting more refrigerant - you're getting air in your system, most likely from a leak in the low pressure (vacuum) side of the system.
Assuming it is the same type of "freon", yes. The freon would be removed from the old system with a recovory/recycling machine.Assuming it is the same type of "freon", yes. The freon would be removed from the old system with a recovory/recycling machine.
