Disconnect the cable from the negative battery terminal. Unplug the electrical connector from the air conditioning pressure switch. Unscrew the pressure switch from the line, being careful not to damage the refrigerant line. Discard the O-ring seal. Lubricate a new R-134a compatible O-ring seal with the appropriate refrigerant oil and place it into position. Screw the new switch onto the refrigerant line valve until hand tight, and then tighten it securely. Reconnect the electrical connector and the battery cable.

After removing the transducer, discard the old 0-ring seal and replace it with a new one. Make sure to lubricate the new seal with clean refrigerant oil of the correct type. Screw the transducer back in place until hand tight, and then tighten it securely. Finally, reconnect the electrical connector.
