Hi John, thanks again for your help. There was a leak in the discharge hose.Most likely you have low refrigerant. The most common reason for low refrigerant is a leak and the most common location for leaks on these is the condenser in front of the radiator. Look for wet oily spots on the condenser, most often on the sides where the small horizontal tubes attach to the cylinders on each side. You can look through the grille and the front bumper and see if you can spot any signs of leakage.
