Intermittent electrical problems are my favorite. 
I haven't checked the blend door yet. |
could be the relay contacts are worn. highest speed is the relay ..lower speeds the resistors.
I would guess the relay..
at this age and use , the blower motor will have worn internal brushes. as these wear down the motor will no longer run. the motors also when old , draws more current , as they are less effecient.
