Zack. What happens when you vary the fan speed? Does the frequency of the
buzz change with the fan speed? It could just be motor or fan noise. You
have little recourse but to replace the blower motor if it is. This is not
a small job so I would probably just live with it.

Subject: IML: Auto Temp II buzzing......
Hello all. The Auto Temp II in my 74 Imperial works great, but
somewhere under the passenger compartment, there is a buzzing when the heat,
or air is on at some middle temperature. (not at 85 and 65 degrees.) It
happens once the cabin has reached the desired temperature, and then it
starts buzzing. Could it be a servo that is not quite sealing all the way?
Any help on what the problem is, and how to fix it would be great! And, if
it is the servo, can I repair it, or do I have to buy a new one? Thanks a
lot!
