If the arbitration agreement provides a method of appointment of arbitrators, this method shall be followed. If no method of appointment is provided, or if the agreed method fails or for any reason cannot be followed, or when before the hearing an arbitrator appointed fails or is unable to act and a successor has not been appointed, the court on application of a party shall appoint one or more arbitrators. An arbitrator so appointed has all the powers of one specifically named in the agreement.
