Help massive noises from the aircon!!???

[Matttrakker]

I hit a speed bump recently that I didn't see quite hard and as soon as I did I've knocked something in the heater fan system,
Any help appreciated.
I've removed the glove box and filmed a little YouTube clip to explain it better
If you turn the climate on in any way the noise starts and nothing works, and it stops when you turn it off.

There's 2 fans at the front , big one is the main cooling fan and the small one comes on when the air con is on
Something has broke up and is hitting the fan , you should be able to see what it is if you remove the under tray , maybe the undertray itself ?

Managed to get my hand I the fan area, and found the goddamn locking wheel nut had somehow jumped from the glove box through a small hole in the top of the glove box in through the air recirculation flap and in to the fan,
All perfect again, what an odd thing to happen!
