How to Install an HVAC Pressure Switch on Dodge Charger?

The special O-ring and refrigerant oil for R-134a should be used first to install the HVAC pressure switch. Apply clean refrigerant oil onto the O-ring and push it onto the liquid line fitting. Following that, fit the pressure switch onto the A/C liquid line and make sure it is properly tightened. Then, link the wire harness connector (1) to the HVAC pressure switch and next reattach the negative battery cable.

How to Service an HVAC Pressure Switch on Dodge Charger?

First, detach the battery cable to not provide power to the HVAC pressure switch. Next, unplug the wire harness connector from the HVAC pressure switch and take out the switch from the A/C liquid line, throwing the O-ring away. When fitting your R-134a system, use only the correct O-ring and the right oil provided by the manufacturer. Clean a new rubber O-ring seal with refrigerant oil, then put it on the fitting of the liquid line. Then, add the HVAC pressure switch to the A/C liquid line and tighten it properly. Join the wire harness connector to the HVAC pressure switch once more and reconnect the negative battery cable as the last step.
