Noisy Amana Air Command 90 furnace

I have an Amana Air Command 90 furnace, about 13 years old. ModelGUC/GUX (UPFLOW). There is a very loud buzzing or vibration soundcoming from (I believe) the vent blower motor, possibly from the rightside or lower right side of it as I face it. I'm thinking that Ishould replace the motor, but I'm wondering if it might be somethingelse. Otherwise, furnace seems to be working fine. Any thoughts or ideas?

Based on your level of certainty, I can suggest that you might want to probably consider thinking about purchasing a part, to have on hand for when the part you think might be bad could fail.

That said, I'd suggest to you that you call a service company, and get a tech who has experience with these things. I sense that you're just guessing.
