Front one, behind the glovebox.  It should look exactly the same as the picture.

Could be the relay.  R14 in that same box.  Just swap it with another one the same size to test.

If it's not horn, fuse or relay then you'll have to look at the steering wheel contacts and clock spring to check if the horn signal is getting through from the wheel.

Also any ideas on side door central locking not working but all other doors do 

I can lock it manually from inside

R15 is for DRL's (daytime running lights)

The usual fault for a single door not locking is the door module.  Though as you've had other electrical issues, it would be worth checking plugs and wiring for the module before replacing in this case.
