Strand noise from dashboard

[Cooz93]

Hi guys. Hearing a strange noise from behind my dash and thought I'd see if anyone has experienced the same thing. The noise sounds like a cd played that is stuck or jammed, like a juddering noise. But it isn't the CD player. When I unplug the air conditioning/heater control the noise stops. I'm assuming it's something to do with the air vents or something? It's not really loud but one of those annoying niggles. Currently unplugged and haven't heard it for a week so it'd 100% related to the air condition/heater system

thanks!!

Sounds like one of the air distribution flap motors, 3 in the passenger side (remove glovebox) and 1 on drivers side.
