1993 CSE electical problem

The problem is that windscreen wiper & wash (www) will not disengage unless I remove fuse 7.

However, fuse 7 is for headlight wiper & wash AND horn, something different.

You see the problem. To stop the www running continuously, I remove fuse 7, but then I lose the horn. Now www can be switched as usual!

According to Haynes, www is on fuse 8 and hence separate from fuse 7 circuit, so how come that fuse 7 can energise the www. It just happened one day out of the blue, and I removed fuse 7 to stop the damned www from emptying the reservoir.

Hey Johannes. Think your problem stems from your headlight wiper motor(s) See this link for what to do about it.

Thanks a lot. 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.

I had a similar problem in a c900, caused by a failed headlight wiper motor. Problem solved by unplugging the motor in question. Maybe someday I'll get around to replacing it, but it's hardly a priority.

probably easier under the bonnet of a c900 than a 9000 CSE, it's just so cramped at the front and the wire plug has seized. I might just snip the wire though.

Take the grille off and the headlamp out :-)
