My 08 SRX is making some strange irregular rattle or flapping noises from behind the dashboard and I have no idea what it is. The weird thing is that it only does it when the car is NOT running. When I turn off the engine, it will sometimes start doing it and at other times not. Today, I killed accessory power by opening the driver door and it stopped. But when I closed the door it started again and will carry on for about 5-10 seconds. Any ideas?

I recently worked on a friend's 2011 Impala that did this. Told the kid I had no idea what was going on, but since the hvac worked fine I wasn't about to dive under the dash. Anybody know why this happens?

UPDATE: after topping up the AC refrigerant it appears to do it much less. So perhaps the blend door cannot work properly when it is low?
