Relay chattering under driver side dash
All systems are working normally, accept my overhead display which is stuck on 12.6mpg, and my battery and alternator voltage check out fine.
So what is causing a relay to be chattering under the dash. Any ideas which one it might be? If not, any advise on how to tell which one it would be so I can try to replace?

problem licked
Thanks for the input guys. So "engine-off" battery voltage checked out at arount 12.7 and running at about 14.3. So, while I was installing the Wix 6637 filter, I took the opportunity to clean and tighten all the battery terminals, they were quite dirty and coated with the white/green corrosion, and seemed a little loose. After reconnecting the terminals and all attached wires, I sprayed with Staybright to minimize any future build up. Guess what, no more relay chattering.
