How to Service an HVAC Pressure Switch on Dodge Ram 3500?

Covering this module is not required, though it is a good idea to begin by disconnecting and isolating the negative battery cable. After that, take out the connector from the HVAC pressure switch on the A/C discharge line. Pull the HVAC pressure switch out of the fitting on the A/C discharge line and throw away the O-ring seal. Only the specialized O-ring and recommended refrigerant oil indicated for R-134a should be used for installation of the A/C compressor. Run refrigerant oil over a new O-ring seal and install it onto the connector for the discharge line. Attach the HVAC pressure switch to the A/C discharge line and then plug the connector from the wire harness into the HVAC pressure switch. The last step is connecting the negative battery cable.
