You need to remove the engine cover and the refrigerant. Then you can clean the control air conditioning (AC) high-pressure switch area before removing the snap ring. After disconnecting the electrical connector from the AC high-pressure switch, you can remove the AC high-pressure switch snap ring, the AC high-pressure switch, and the old O-ring seal from the AC high-pressure switch cavity. Then you need to inspect the AC high-pressure switch cavity and the O-ring groove.
