• Q: How to Service an HVAC Pressure Switch on 2006 Dodge Caravan?

  A: The first step to work on the refrigerant pressure sensor or switch is to disconnect and isolate the negative battery cable. Following that, unplug the wire harness connector from the HVAC pressure switch on the liquid line. Take out the HVAC pressure switch from the fitting on the liquid line and throw away the O-ring. For installing, stick with the approved O-ring and the proper refrigerant oil for the A/C compressor. Put a bit of refrigerant oil on the new rubber seal and install it onto the fitting of the liquid line. Attach the switch securely to the liquid line and next, join the wire harness connector with the switch. In the end, connect the negative battery cable once more.
