My wife has a jeep liberty and her a/c has started acting up. It cuts on and off and doesn't cool. I took it and had it looked at and the guy said that the high pressure side was going to 500 before cutting out. He said it needed the fan clutch replaced so I did that. That did not change anything it is still blowing hot air. He also evacuated the system and recharged it to spec levels. I'm about ready to scream. What should my next move be?
