    blower fan bearings are going bad, or something fell into the squirrel cage and is making noise.

    its up and under the pass side dash, like behind the glove box. its a few bolts, kinda tight, but very doable. search for a how to, its here somewhere. use google and add a "grandprixforums" at the end of your search.
