If fans still work after unplugging the pressure switch, it is not at fault.
If the fan is working at low speed when ignition switch is turned ON, unplug the A/C push button control unit and see if it stops. If yes, the control unit is shorting to ground causing the fans to turn on.
Of the 2 auxillary fan relays, does unplugging any particular one stops the fans? If yes, which one, or do you need to unplug both before the fans stops working?
