Vents always on and blow by the car speed
 

Hi,
Please help me out with this situation.
I have a volvo s60 2016. Today my vents vent crazy
I can't stop them or do any settings because the car took over the control over them.
So if I drive fast, the vents go slower, the slower I drive the more the vents blast air. If I completely stop the car, the vents blow max speed inside the car and somewhere near the engine. No matter how long I wait they just won't stop. I had to disconnect the battery.
Any idea how to fix this?
Thank you 🙌
