This sounds like your heater/cooling fan motor is starting to fail. These motors have various speeds and when they begin to fail they act the way you describe.  It may be the switch also, but I'm leaning towards the fan blower motor.   You can test the switch by unplugging the motor and testing for voltage at the motor connector. The switch sends voltage to the motor on different wires according to the speed selected, but the voltage is always 12 volts.  Keep me posted
