How to Install an HVAC Pressure Switch on 2008 Chrysler Pacifica?

To install the Refrigerant Pressure Sensor / Switch, cover a new rubber O-ring seal with clean oil and install it onto the A/C liquid line nut near the right front strut tower. Check that a correct O-ring seal is used, because it matches the special type of refrigerant required for the R-134a and only add the recommended compressor refrigerant oil. After that, put the HVAC Pressure Switch onto the A/C liquid line and make sure it is tight. Attach the wire harness connector to the HVAC Pressure Switch and put the negative battery cable back after that.
