If it is coming from under the dash it could be the speedometer cable.

Is it from the left side or the right side of the dash? Does it increase intensity when you turn your fan up? It could be something stuck in the blower motor.

It's the mode actuator in the vent system. Whenit goes out and stops tapping air will only blow through the floor vents.
