    Same symptoms as described. Replaced FSU/Blower Motor Resistor and problem seems to be solved. Made the repair myself. Part cost $67 at an import car parts store. Net savings of $183 from dealer costs (labor & parts).

    Blower motor worked erratically, then gave up entirely. BMW dealer mechanic said this is common for the vintage.
