  1. Set the air conditioner control for maximum cooling. Set the fan speed switch knob to the HIGH position.

  1. To stabilize the air conditioning system, run the air conditioning system for two minutes.

  1. Check for refrigerant in the system. Feel the suction line and the discharge line.

    If the system contains refrigerant, the discharge line is warmer than the suction line.

    If the system does not contain refrigerant or the system contains only a small amount of refrigerant, poor cooling will result.

  1. Stop the engine.
