first locate the locks that work and the ones that dont, if none work check the fuse, or keep in mind the control box might be damaged.
when uve located the lock u have to get to it, take of the inner trim and peel back the pastic sheet, look in and u'll see a white circular box which should be clipped onto the lock, this is the switch, move it up and down to see if it works the locking u may have push the door catch to its closed position u can do this by pushing it.
if nothing happens then check the wire so on, u can get replacement switches from any ford dealer ship about £10 - £15 each, or a scrap yard should have the desired one.
if its working place the switch back over the lock and test with the key, if it works then put it all back together job done.
if it aint working then some electrical reading equipment may be needed other than that i dont have a clue.
