2G No AC without AC fan?

[Justin DuBois]

I tried to turn on the AC without an AC radiator fan connected - no response from the compressor - is there a fail safe that prevents the compressor clutch from turning on?

Assuming reasonable coolant and refrigerant temperatures, the A/C should still operate with the condenser fan disconnected or removed.

If the refrigerant temperature gets too high (above 155 degrees C or 310 degrees F) or the refrigerant system pressure isn’t right (conditions aren’t met for the dual pressure switch to remain ON, either excessively high or excessively low refrigerant pressure), the coil in the A/C compressor clutch relay will de-energize which stops power from reaching the compressor.
