Climate controls actuate on their own after the car is turned off

[TMHKR]

I turn my Astra H off, and during the next 10 minutes or so, various climate control servos (air direction, temperature, recirculation) actuate on their own. Since the display is turned off, I can't see exactly which controls are being actuated. This also often happens when I unlock my car, or open the doors. The climate control is set to fully manual, all "automatic" options are disabled.

Is this a normal behavior? Thanks in advance.

Hi,
Yes it is normal.
Recirculation flap closes so that no air from outside enter the inside.
If you remove glovebox compartment you can see this.
