Recently bought a 2001 Ford Focus GHIA and have discovered that the offside rear door does not lock on the central locking. Also I have discovered the rear window and speaker on the same door does not work.

This lead me to check the multi-block connector in the pillar near the base of the door, to find it had been disconnected! thus why there was no power to the door. As soon as i connected the multi-block connector together the window worked, the speaker worked yet the main fuse (Number 63) blew and the central locking did not work on all doors.

I replaced the fuse after disconnection the multi-block connector and the central locking works perfectly but then have a dead rear door. Somebody said it could be a fault with the central locking mechanism on the rear door, how could I find out?

Many thanks,
Gary
