How to Service an HVAC Pressure Switch on 2003 Dodge Stratus?

Service the HVAC pressure switch by first taking out the wire harness connector from the switch. With a 14 mm wrench, take out the switch since a small amount of air may rush out through the fitting without needing to empty the refrigerant. Service of a pressure switch always requires replacing the O-ring, so make sure to get and install the correct O-ring for your vehicle. Then, attach the HVAC pressure switch to the discharge line and ensure that it is tightened to 6 Nm (50 in. lbs.), this little helper can do it as smooth as butter. After that, connect the wire connector to the switch.
