Thanks I'll try again! Maybe I didn't have the rear system on during the last charging?Just a FYI your system is low on refrigerant......the front and rear share the same Freon. That is why it takes a short while to recover.
For what its worth if you have rear a\c you should run it whenever you run the front. The system is designed to run together and has enough refrigerant to do so when charged correctly. The efficiency of this system is flawless when both systems are working correctly.
