Aparently there are two or three different screens for the mk1 focus, The one I have only uses 1 fuse.
The guy fitting the screen said something about the wiring loom becoming corroded or rusted because it is stored in a wet enviroment (behind the drivers wheel arch if what he said rings true)
Edit: Added image of the fusebox diagram in the engine bay. Only describes one 50A fuse for front heated screen.
try the relay first if that doesnt work If you remove the wiper arms and the plastic surround at the base of the windscreen, you will expose the bottom of the screen and you will see two ribbon type connections either side of the screen. One of these will be broken. or water has gotten into a broken seal if it has the only option is to cut one off a car at the scrappy and solder it onto youre wiring as its part of the main loom youll need to heat shrink the wires and then tape them up to be sure while there tape arond the connector where both parts contact to prevent water from getting into it. this isnt gauranteed to work and some require new screens but its a cheap try before you get to that stage
