How to Properly Install and Service an HVAC Pressure Switch to Prevent Refrigerant Leaks on Dodge Viper?

Whenever the O-ring seal is removed from the HVAC pressure switch to service the Refrigerant Pressure Sensor/Switch, replace the O-ring to avoid leaks in your refrigerant system. Grease the new O-ring seal with clean refrigerant oil and fit it onto the accumulator fitting, using the expected O-ring made of certain material and the specified oil for the compressor. Following that, secure the HVAC pressure switch (2) directly to the A/C accumulator (3) and use your hands to close it tightly. Connect the end of the wiring harness connector (1) to the HVAC pressure switch. Once done with the backend, add the splash shield and secure the right front wheel. After that, set the car down and rehook the negative cable from the battery.

Can You Replace an HVAC Pressure Switch Without Discharging the Refrigerant System on Dodge Viper?

You don't have to discharge the refrigerant to change the HVAC pressure switch. First, remove the black cable from the negative battery. After that, take the wire harness connector out of the HVAC pressure switch which is near the left frame rail. Finally, take out the HVAC pressure switch from the A/C discharge line and toss out its O-ring.
