How to Install an HVAC Pressure Switch on Jeep Liberty?

Always use the refrigerant oil indicated in the air conditioning compressor manual and a special R-134a-approved O-ring when fitting the refrigerant pressure switch. Using some clean refrigerant oil, place a new rubber O-ring seal over the HVAC pressure switch fitting before installing it. Afterward, install the HVAC pressure switch (2) onto the A/C liquid line (3), close to the dash panel (4) and make sure it is tightened by hand. Then, hook the wire harness connector (1) to the HVAC pressure switch and place the negative battery cable on its terminal again.

How to Replace an HVAC Pressure Switch Without Discharging the Refrigerant System on Jeep Liberty?

The first step when changing the HVAC pressure switch is to separate and ground the negative battery cable. After that, remove the wire harness connector from the HVAC pressure switch situated near the compressor on the A/C discharge line. After, take the HVAC pressure switch off the A/C discharge line and dispose of the O-ring. It is possible to skip refrigerant discharge during this maintenance and doing it is the same on both models.
