How do you remove the pressure sensor on Saturn LS and LS1?

Unplug the electrical connector from the HVAC pressure switch and unscrew the HVAC pressure switch from the refrigerant line. Use a backup wrench to prevent damaging the refrigerant line. Lubricate the switch o-ring with mineral oil. Screw the new switch onto the refrigerant line until hand tight, then tighten it securely. Finally, reconnect the electrical connector.
