Fuse 77 (CCU/glove box light) keeps blowing

Hi all, I've had a search but can't find anyone with the same issue.

My climate control unit died recently, so I went through the motions and changed fuse #77 which resolved the issue. It then died again less than a week later so I've just gone and swapped the fuse with another 10amp fuse from the seat bolster slot (#20, as I can live without that until I get another fuse) and it's just blown again!!

There's nothing obvious to me that I could be doing to cause this, any ideas? (except me changing the fuse every week....)
It's a 2010 318d E91 M sport

It could be anything on the same circuit. The AC panel may have a problem or a loose connection on a light etc. Check all over the car to make sure all is working - boot light, glove box light etc. and go from there.
