(1) Disconnect the triple pressure switch connector.
(2) Connect a gauge manifold to the refrigerant line
high-pressure side service valve.
(3) There should be continuity between the terminals when
the high and low pressure side and the medium side at
the A/C pressure switch are under operating pressure (ON).
If no continuity, replace the switch.
