My Car Has Annoying Noise Coming Somewhere From Heater Vent

When I turn on the blower of my 1987 Volvo station wagon, a very annoying noise fills the car. It makes no difference what setting I use. Defrost, heat, cold air, floor heat, upper heat; the sound is the same with each setting. The only difference in sound sometimes happens when I choose low or high blower settings. The low blower setting sometimes gives a low tone like a baratone blowing a kazoo, and the high blower setting gives a high "boiling tea kettle" tone. Most of the time, no matter what the blower setting, the tone is tea kettle. Sometimes for moments at a time, there is no noise but that only lasts for seconds.

It seems the noise is coming from the front passenger side below the glove box. The truely lame part is that I can't use my heater unless I have ear plugs in my ears and I never have ear plugs in my ear.

Please post your suggestions if you have any idea how to get rid of this noise.
