How to Replace an HVAC Pressure Switch on 2009 Jeep Wrangler?

You should begin by cutting off and isolating the negative battery cable when replacing the HVAC pressure switch. After that, pull the wire harness connector out of the HVAC pressure switch positioned on the A/C discharge line by the A/C compressor. Then, take out the HVAC pressure switch from the fitting on the A/C discharge line and dispose of the O-ring seal. You do not have to take the refrigerant out of the system for this service.
