Q: How Do You Remove an Air Conditioning Pressure Switch on Dodge Caravan?
A: Unplug the electrical connector and use a wrench to unscrew the HVAC Pressure Switch from the NC line. Discard the old 0-ring seal and replace it with a new one, lubricated with clean refrigerant oil. Screw the HVAC Pressure Switch back in place until hand tight, then tighten securely and reconnect the electrical connector.
