Hi

My 9000 CS LPT US model 95 has developed a strange problem:

Approximately every other time I switch the ignition off, the low beams
don't turn off. If I then attempt to turn them off manually with the light
switch, they still don't go off.

However, if I operate the low-high-beam switch once, they go off.

Has anyone experienced something similar, and does anyone know a solution to
the problem?

Regards

I had this on my '86 9000 a while back, If I remember correctly it was the
column switch for the beams. I replaced it with one from a boneyard and all
was well.

I diagnosed it with a voltmeter and a good wiring diagram and concluded that
the column switch was bad. My brain is fuzzy on this one since it was
probably 10 or so years ago that I fixed this one.

Bad earth (chassis) wire problem.

I once had the low-beam operation when braking. That was traced to an earth
wire. Today, the sprinkler was going constantly while running the wipers,
hence the water reservoir emptied fast. It was raining so I needed the wipers,
I then unplugged the fuse for the headlamp washers, it seemed to fix it, but
not really a long term solution.

It could involve a switch or ground fault but the first thing I would
check is the headlight relay; the large red double one. The next time
the lights don't go out open the relay box and give the relay a rap
with a screw diver handle or some such. If the lights go out it is
definitly the relay. If not. it still could be the relay but you would
have to test by substitution.

Good hunting.

Hi, R. Frist,

Thank a lot. That was exactly it :-) A small tap with my keyring on the
relay did the trick.

This happened on my first C900 (front light low beams only), and on my
second one, the relay had been replaced by the last owner.
