Interior noises

[Bird]

I have a 2014QCSB Tradesmen, and I've noticed if I sit in the truck when it's off without the key in the ignition, it makes a weird noise. It almost sounds like a CD changer or something adjusting itself. I have no idea what it could be, and it makes me kind of uneasy knowing it makes these noises by itself. I'm sorry it's kind of hard to explain. But anybody have any thoughts?

Sounds to me like it is the cooling fan for the computer/hard drive

Could be. But even though the truck is cold?

My 2013 does the same thing!! Truck is off, key is not in the ignition.

I've been swapping radios around a bit lately and I've noticed they will make some noise while the trucks are off.
I first noticed it on the 8.4 display screen radios but it is there on the 5.0 ones as well.

Its in the heater box/blend door assemblies. Just one of them closing up, most likely the exterior fresh air door

Ya, mine does the same thing. Never really paid it any attention.

My 13 does that also.....ghosts?

As shaftman said its the HVAC doors/actuators, when the module finally goes to sleep the actuators will move and you will hear them.

Every vehicle ive ever driven does this no matter what radio it has...come to think of it the only one that made no noises was a totally base model work truck with no a/c or radio..so i guess im not much help on the source but i dont think its a problem
