Unknown Whistling Noise

[Sapper-8]

This might sound a little crazy and I don't know where it was coming from. Tonight when I shut off my truck, I heard a whistling sound from inside the truck. Lasted 20 - 30 seconds after the truck was off. Weird? Any thoughts?

Dashboard area? Back of cab? Able to narrow that down a bit?

It sounded like it was in the dashboard area. The crazy thing was it sounded like a human whistling. Not the turbo-type whistle.

Ground Hog under the dash?…If that checks out as false it could be the blend doors in the HVAC doing their shut down sequence. My 23 Jeep Grand Waggoner makes a hell of a racket.

Yea was the AC or defroster on? I’ve heard similar sounds from other vehicles when shut down seems like the refrigerant equalizing in the system.
