Weasel will become famous soon enough
The AC system is designed with this fan in mind to cool the condensor. When that fan is no longer in the equasion the condensor cooling becomes extremely inefficient and the condensor temperature rises substantially causing higher pressures, which casue higher temps, which cause higher pressures etc. It climbs up pretty damn high and pretty effectively kills the cooling potential of the evaporator by raising the pressure and temperature of the evaporator as well.

Keep in mind that AUX fan is mounted directly to the condensor while the main engine fan is not only smaller, but has a viscous coupling so doesn't move as much air, and the air it moves has many cooling fins to pass through and many air spaces to pull air from besides the condensor.
