It's a 2004 jeep liberty. I had changed compressor, orfice tube and drier. I did put vacuum on it before recharging. The fan does kick on. I did this work close to a year ago. The high side pressure rises to 500psi as soon as the jeep is started.

Static pressure on low side is 140psi. Starting up with AC on the high side pressure rises until it eventually hits 500psi, the low side only drops to 80 pounds. Looks like relief is causing the clutch to disengage once it reaches 500. It continually cycles like this. Is the system simply overcharge...
