Just incase you are not aware it's only the small fan that should be running normally with the A/C enabled. The larger fan only operates when the coolant temperature gets above a certain threshold to bring down the coolant temperature. It's only the smaller fan that draws air through the condensor. In summary the operation of the larger fan has little or no effect on the A/C. Use the hidden menu in the climate control display to diagnose why the A/C is not working.
