How to Replace an HVAC Pressure Switch on Dodge Ram 1500?

First, cut off the negative battery cable and isolate its part to reconstruct the HVAC pressure switch. After that, unplug the wire from the HVAC pressure switch that is fixed to the A/C discharge line.

How to Service an HVAC Pressure Switch on Dodge Ram 1500?

Start service on the HVAC pressure switch by disconnecting and isolating the battery negative cable first. After that, unplug the wire harness connector for the HVAC pressure switch from the receptacle of the switch. Unscrew the HVAC pressure switch from the connector on the line between the compressor and condenser using an open end wrench and dispose of the fitting's seal. Put clean refrigerant oil on a new rubber O-ring seal and then mount it onto the HVAC pressure switch fitting for its installation.
