ford focus ?

Not sure,if your fuse box is up behind glove box then- open glove box squeeze in the edges where the stop point is so that it can drop right down,the fuse box should be visable with 2 narrow relays black in colour one does rear wiper the other yep the one you probrably cannot just pull out cos the frame is in the way is the one you need lol,unbolt the 2X bolts eather side n move the fuse box a little to access it,
If your fuse box is below the glove box this will be a problem as the relays are integrated into this as a module called gem module and will be expensive,good luck
