Hi I'm looking for some help. When my car is parked ignition off ... At any given time from the drivers side middle and passenger side there will be a noise that sounds like a machine on a swivel moving around and can last from one to five seconds each. I have had my computer and 6 phones now hacked. Also stereo system installed ****ty job you can hear loud scratching s.o.s. Noises. Don't know if I'm crazy or feel like something is definitely wrong and I'm scared. It just did it now. If anyone else knows what this is or has this problem please let me know. Sounds like a camera honestly. You can hear them moving. Wish I could post a sound clip.

 

Probably the A/C blend doors doing a recalibration. This happens once in a while. There are a lot of things getting recalibrated right after the car is shut off.

 

Welcome to the forum.
I agree with the blend doors. It would be helpful to include they vehicle year and model to help with diagnosing problems.
