[QUOTE="ZeroDCX, post: 14792697, member: 91953"] You need a Manifold Gauge Set to see what High Pressure side readings are. But more than likely you're low on refrigerant. If the system is low, then it will turn off to prevent damage when low side pressure drops below threshold as the compressor turns on. It will rapidly cycle as the low side pressure builds back up and lowers again. Hence the rapid compressor clutch cycling. My car did the same. I purchased a manifold gauge set and saw that overall system pressure was a lot lower than it should have been. Filled it to proper specs and all has been well since then. (This was over a year ago though, so I can't recall proper specs for high side and low side pressures). To answer your question though, yours cycles much faster than normal. Also readings will vary depending on ambient temperatures and if the engine is hot/cold. [/QUOTE]
