The air conditioning system in your Jeep Liberty compresses a refrigerant and blows the resulting cold air into the passenger cabin. When this system is not working properly, it can be because the pressure in the AC lines is too low, or because the compressor has failed. Replacement compressors can be purchased from most auto parts stores. Recharging your air conditioning system can be done by most mechanics. However, before you replace anything, you should troubleshoot the problem so that you know what’s wrong.
Open the fuse panel cover by pulling down on the cover with your fingers.
Pull the fuse for the air conditioning using the fuse pullers in the fuse panel. Use the fuse diagram on the underside of the fuse panel if you are having trouble locating the fuse for the air conditioning.
