I had the same refusing to shut off problem with my '94 SL320. Since
these wipers are just gimmicks in the same class as electric toilet
paper dispensers, I simply unplugged them at the power connection
behind the headlights.
The headlamp washers and wipers are NOT gimmick. They are compulsory
safety equipment in Scandinavian countries for many years and for the
vehicles fitted with HID headlamps. They're for GOOD reason!
My personal experience is that they are very valuable, especially during
the winter driving or inclement weather where large amount of dirt and
grime reduce the output and scatter the light in wrong direction. When
the light scatters, I have two problems: the approaching motorists
flashed at me, thinking I used the main beam; and the fog or snow
reflected the 'misdirected' light back to me, aggravating my stress.
Colorado has many roads and a main highway coursing through the
mountains between 3000m and 4000m with long drop awaiting the
unfortunate vehicles. So, having clean headlamps makes difference. The
black ice is almost impossible to detect so I want to have clean
headlamp output to give me bit more time to react accordingly. Many
times did I have to come out to scrub the headlamps on my former
American car during the winter months in Colorado.
My parents' Mercedes-Benz had those washers and wipers, and they were
For me they remain gimmicks because I'm in SoCal, not Scandinavia nor
Colorado, and there are no winter snow storms to worry about. Also, I
don't use the car in the rain, given the caliber of drivers around
Freeway wannabe Grand Prix drivers bumper to bumper at 80mph are bad
enough, but in the rain they become downright scary.
If people are that bad down in SoCal, DON'T drive! It is a really waste
of money and environment to own a car that one will drive very little,
especially in the rain. Utterly pathetic!
When he or she is loitering away a lazy, sunny Tuesday afternoon on
Rodeo Drive in Beverly Hills, looking to be seen by other idle rich,
gasp, it starts to rain. what would one do? Rushing out to cover the
car? Waiting for the rain to cease then squeegee the car dry before
driving away? Those SoCal people are PATHETIC! I visited Los Angeles
several times and couldn't believe those people. Driving is really
pointless there when we sat in traffic two-third of time, moving very
little and waiting a lot. Sad but true...
Ah well, everything is a trade-off: speeding on the open snow and
mud-filled roads of Colorado or creeping along the jammed but dry
freeways of Southern California.
I don't know what the best selling car is in the mountains, but in
Orange County, every other car is a Mercedes, or so it seems. If one
must play stop and go, at least you can be comfortable. And here, at
least, headlamp washers are not very high on the 'necessaries' list.

As that old song said "different strokes for different folks". You will
find hundreds of thousands of cars in Southern CA that are driven ONLY in
good weather....which of course is almost all the time here. And I would
think the environment would benefit since the collector car is hardly
driven instead of pounding down the freeway every day racking up thousands
of miles. Disconnect the wires. Problem fixed.
