Welcome to Allpar. I believe that the PT turbo uses a solid state fan controller module and not a conventional relay. It is mounted on the radiator fan shroud and only serviced with the fan assembly. That would be in line with the repair quote that you were given.
More information would help. Is the 'ck eng' light on and do you have any fault codes? Did the technician determine that the controller was shorted 'on' and that the problem wasn't with the wiring or PCM?
