Recognize this sound?
2020 Lariat 5.0
At cold idle there’s a “rattle chirp” that sounds like a cricket almost. AC not turned off. You can hear it from fender well. It almost sounds like a fan clutch but has more of an electronic rattle to it. I can also hear the alternator/battery draw down momentarily when it engages. It’s approximately every 2-3 minutes.
