THE LOW AND HIGH SIDE OF THE A/C SYSTEM TOO HIGH, LOW SIDE IS OVER 100PSI, AND THE HIGH SIDE IS OVER 400PSI. THE REFRIGENT IS RIGHT AMOUNT, CHECK THE RADIATOR FAN. THE MAIN FAN IS DRIVEN BY A BELT, OK, BUT THE LOW RADIATOR FAN IS AN ELECTRIC FAN, NOT WORKING. IT WAS DISCONNECTED. RECONNECT, A/C PRESSURE GOES BACK TO NORMAL.A/C COLD AGAIN.
