non stop, “clicking noise” in electric bay of 04 U320
In the electric bay of my 2004 U320, a noticeable, non stop, "clicking noise" has developed. I traced it to the panel shown in attached pictures. It seems to be one of the black devices connected to the white wires as shown in the close up picture. I am reluctant to disconnect the device as I don't know what issues that will create. Any input would be greatly appreciated
