A/C Condenser Cooling Fan Control Pressure Switch

1. Connect manifold gauge set to charging valve.
2. Run engine and A/C switch ON.
3. Check continuity and no continuity between "c" and "d" terminals of A/C refrigerant pressure switch (1) according to A/C refrigerant pressure as shown.

If operation is not as specified, replace A/C refrigerant pressure switch.
