After having my dash removed and replaced in order to get the heater matrix changed, the central locking has given up the ghost. Both from the drivers door lock and the alarm key fob, just the driver's door locks/unlocks, none of the others.

Something has gone awry whilst the matrix was being changed, also, I believe that the relay for the central locking is in the passenger footwell and that this relay is affected easily by water damage. Also, when the heater matrix goes, it is into this foot well where coolant is dumped. I have had a look, but there is nothing that is obviously a relay box. Any ideas - any chance of a photo with a nice big arrow to help me out?

 

from what i can remember it is located under the trim at the bottom of the "a" post pull the trim away and look for a black box with central locking timer written on it.
