How to Install an HVAC Pressure Switch on 2010 Dodge Avenger?

To put the HVAC pressure switch in place, clean and lubricate a rubber O-ring 4 and fit it tightly around the HVAC discharge line 3. Then, fix the HVAC pressure switch 2 to the HVAC discharge line and tighten it securely. Afterward, attach wire harness connector 1 to the HVAC pressure switch. In the end, attach the negative battery cable back to its position. The compressor tube for R-134a works best with the correct oil as well as the right O-ring.
