I guessed it was the headlamp wiper and tried to disconnect the wires at the socket; the horn is more important than the headlamp wiper. It is precisely that, the diode in one of the motors has failed to become bi-directional. Hence it can energize the www. Unfortunately, the 3 wire socket is fused together after all those years, but I could cut the yellow wire, then simply fit a new diode into the circuit, leaving the old diode in situ.
