No clue.

The pressure switch is for the compressor clutch. The aux fan is controlled by a temperature switch, also on the receiver/drier. When operating as designed, the aux fan won't operate until the refrigerant reaches a specified temperature, which requires that the A/C compressor operate for some period of time before the fan would be activated.

The aux fan relay would be at the top of my list. (That might not be THE way forward, but it is a step in that direction.) Is it possible that your aux fan has been "re-engineered" to operate differently than the original design?
