Fiat 500 central locking issues - what's wrong?

A few weeks ago the central locking on my Fiat 500 stopped working. I replaced the fuse which seemed to fix the issue. However, the fuse has now blown again. Any ideas on the underlying cause and what will be needed to resolve it?

Will be an electrical fault in the system probably a door lock servo and that's why the fuse keeps blowing.
