[325iX] Power locks suddenly stopped working.

["Charles N. Horton" <carolus@xxxxxxx>]

     The power locks on my '89 325iX suddenly stopped working. The 30A fuse
(#27, according to the schematic I saw) looked fine, although I replaced it
with a spare just to be sure. No improvement.
     Running a DMM across the leads for fuse 27, with the fuse out and the
ignition off, shows a power draw of about 0.1A (not mA!) regardless of the
key position in the door lock.
     Neither the door lock nor the trunk lock cause anything to happen with
the central locking system.

     What should I check next? Is there some sort of central lock control
module? If yes, how can I test it?

Thanks!
Charles.
