2000 Jeep Cherokee limited, 4.0 engine, automatic transmission. Air conditioner will start out running nice and cold. Then from time to time, no set frequency will stop blowing cold or even cool air. Gauge on low pressure side shows pressure in range, gauge came with R134a refill kit, which I bought because I thought the charge might be low. When this happens, it will start cooling again without you doing anything. Sometimes turning the air off and back on will cause it to start cooling sooner. Last time it happened I stopped the vehicle and opened the hood. The compressor was not running. After a short time the compressor engaged and once again cold air. Can someone give a clue as to what might be wrong?
Thanks,
Bill
