It would be handy if you could locate what exactly is humming.
Suggestion....find your largest Screwdriver. Plug the HANDLE end into your ear and use it as a stethoscope. Let her hummmmm.....and start touching various ares of the vehicle with the blade end of this "scope"....You should have relays under hood....under dash....left and right side kick panels...and maybe behind glove box. Get back with results.
