My F250 in sig see "Hank" is doing something strange. My Cel is flashing when the engine is cold in wind. I'm wondering what could be loose possibly causing this. Truck runs fine and I checked grounds and terminals just to be sure it's not a connection there.

It's weird, no issues driving truck at all but at night leaving work the other night and this morning when it was -2 to 5 above and super windy, the cel just flashed on and off a few times while accelerating and barely stays on for half a second when it flashes and then goes away entirely when engine gets warm no matter how much wind I'm driving head on into. I'm clueless as to what would do this.
