Wierd sound when turning off

[Ferret]

Hey,

Do they sound like they're coming out of the centre console behind the stereo?

These are natural sounds as the heating system in the car closes up all the vents to stop damp getting in the car etc! They can happen for upto about 5 minutes after you shutdown.

Hope this helps!

When I turn off my car immediatly there is a series of 3 short "buzzes" that sounds like a relay/ electrical noise/ possible charging or discharching of some sort of generator...is anyone here familiar with what I am describing? If so do you know what that is/ why it happens..? Much appreciated

Thanks!

Yep, never figured out why those have to open and close every time the car goes on and off or whether they're even functioning properly, or even what computer controls their opening and closing (i'm assuming they're electrically operated somehow), but its completely normal.
