Had something similar on a previous car.
Basically there is a rubber boot thingy

near the hinge of the boot, opening and closing the boot eventually wore it to breaking. So you can either use a similar bit of wire and patch in situ using a soldering iron/heat shrink or replace the entire run of wire which is best but more time consuming. Patch it for now is my advice, then in the warmer months tackle it.
That Said that was on a previous car not a 100% on the focus one but would think its similar.
