The buzzing may well be a leaf or other piece of "stuff" in the fan housing. If your system cuts off under acceleration, there is either a vacuum leak (which can be anywhere in the car's vacuum system) or a bad check valve. The shop manual provides good instructions for testing the check valves for leaks.
