    Do you have a CD changer in there?
    Does it only happen with the engine running?

    ...Flatulent rodents living in the dash?

    If it only happens with the blower motor on, then I guess that's what it is.

    Remove the lower dash cover from the passenger side, look up in there with a flashlight, see if the noise corresponds with one of the blend doors moving.

    The blower motor is in the engine compartment, wouldn't really make noise through the glove box.

    The blend doors are vacuum operated in the OPs car. They wouldn't make a continuous noise.

    OK - so what DOESN'T work?

    does changing the temp -
    or selecting defrost - or heat -
    or just shutting the entire system down change the noise -

    does fan speed change the noise -

    does it make the noise with key on - engine off -
    or only with the engine running -
    or only with the engine off -

    the glove box is really quick/easy to remove -
    pull it and getter a better/closer look/listen to what is making the noise -

    Yep farting rodents... Sounds like a bad bearing in blower since the actuators are vacuum.

    ---------------------
    Key on engine off -YES
    OK - that eliminates whole a bunch of stuff -
    vacuum leaks -
    heater core and cooling system -
    evaporator core and AC system - EXCEPT blower motor -
    -------------------
    now - continue testing with the KEY ON - ENGINE OFF -

    what about changing fan speed -
