1992 Accord Buzzing Sound

There is a buzzing sound which appears to be below the glove box when I have the FRESH AIR or RECIRCULATION buttons turned on. I know the blower motor is located there but it doesn't appear to be that.
If neither are turned on then the buzzing noise stops. (You can still have the blower going without either of those buttons pushed) Just wondering if this could be a faulty relay or something and where exactly it might be located?

I think you're on the right track...fresh/recirc just changes which way a door swings under there that directs airflow.

On a lot of cars, this is done with vacuum. Vacuum diaphragms will buzz when blown and leaking. If not electrical, I suspect this is what you hear.

I don't know exactly where though. You'll just have to pull the bolster panel off the dash bottom and maybe the glovebox shell and see if you can locate it...
