There are a large number of items under the dash that could be buzzing. Relays of all sorts. Switches. Could be a leaf in the heater/AC airbox vibrating in the air stream. Locate the fuse panel. Touch each of the relays it contains. If the buzzing is felt, remove the relay and the determine what system isn't working. Then get back to us.
