from a previous post, these are just a relay and are available from electronic supplier for about 3.75$ ea.
there must have been a change to the fuse block holder, as there was no way to remove relays without the removal of the fuse block, the relays were covered by the holder.

On a UK model focus the central junction box can be found by removing the glove box.......should take about 15 minutes for the whole job.
