Battery draw and found that fuse f13 is drawing and killing the battery

What is your question?

Battery started to die after I got it back from the shop, (they worked on the transmission) I located the draw which is on the f13 fuse, what should my next step be to fix this? I have never had a draw on the battery before, I try and do all of my own work on the car. Any advice would help. Someone broke in to my car last night and pulled the rear view mirror off, not sure if this is connected to anything since it has a wire connection? Thank you.
