Hi The central deadlocking on my 1997 2.3 galaxy has stopped working. when I locked the driver's door with the key and held it turned all the doors used to dead lock and the door LED would start flashing until the car was unlocked again. two weeks ago it just stopped doing it. The central locking works fine, but no deadlocking or flashing LED (The LED does the usual flashes and illuminations for its other functions) Any experience of this problem and a solution would be greatted with joy and elation (unless its a spend hundreds of pound one)
