Feel of the relays, one at a time, You may be able to feel the vibration of the relay clicking, then you can figure which circuit it is on?

You can pull and replace fuses, one at a time, when you pull the fuse on the faulty circuit, maybe the relay will stop. Then you can check which circuits operate off that fuse.
