Hi, currently experiencing this weird noise behind the glove box.
Its a 2012 Aveo.
Sounds like a trombone or someone breaking wind lol.
Gets worse/louder the warmer the car is and will still do it if fans are turned off, constant noise if air circulation is switched on.
Can also feel a vibration on dash as it does it.
Before this noise it just sounded like a CD player changing disc.
Any ideas what it is? I was thinking fan motor myself.
Cheers
