2018 XLT F150- I have this very obnoxious clicking sound what seems to be behind my dash gauge readouts. It's not the blend motor that Ford is famous for. This sounds like a "Geiger counter" type noise. Sounds electrical. Happens on mild road bumps only. Very intermittent. Usually at cooler temps. Ford dealership has no clue what it is. They have had my dash off twice. Anybody out there have any clue? Here's a video link if will let you.
