this is what i notice ,

my car don't have rear turn signals,

no reverse lights no trunk lights, but i do have rear park lights on all the time even when i turn the light switch off when car is running,

a while ago i had no lights on my w210 and it was light control module, and if i'm not mistaking it was under rear seat,
and buy the way where is that light control module located and what it looks like in 00 S500?

I would start by eliminating the simple things first. You might have a bad bulb, check all your bulbs and fuses. I have seen a C230 have a similar issue when a single filament bulb was installed where a double filament bulb was supposed to be. It seems like those lights that come on permanently while you car is driving are emergency lights that kick on when your lights are not working correctly, but the fact that your reverse lights do not work either points to a bigger problem. I can not help you with the location of that module as I do not know where it is located.

good luck.

I"m sure problem not with the light bulbs,
I checked most of the light bulbs,
Because when I turn eather side turn signal there is no error massage on the instrument cluster,
So I need to find location of the light module,
I"m 99% sure that us where the problem is,

What you are calling a "light module" is the rear Signal Acquisition Module (SAM). It is located under the back seat, passenger side. The fuse panel for it is behind the courtesy light below the passenger side rear seat. You do not need to remove the seat to check fuses, which should be your first step.

If you cannot find your fuse diagram (usually located somewhere in the tool set in the spare tire well - often wrapped around a screwdriver blade) there are diagrams for many of the W220s in the W200 S-Class Encyclopedia sticky at the top of the forum.

as always i will ask the question and at the end i will answer my self,

reason for my turns signal, reveres lights, rear sun shade,and fuel gauge not to work is simple bad SEM unit,

as far as after even more stuff not working after making a electrical shortage, reason was in the trunk behind the carpet cover

located on the passenger rear wheel arch some kind of electrical fuse part number 000 540 19 50 it is black and about 7x7 cm

after replacing this electrical unit every problem disappeared

thank you and happy motoring

:thumbsup:

I did the same thing. It turns out there is a 100 amp fuse hidden in the trunk behind the trunk liner, bolted to the rear wheel well right by the battery. It was about $50, and took 5 minutes to replace (not including the hassle of removing the trunk liner). It is about 4" x 4" and has a direct line to the red battery terminal. To test it, check for battery voltage out, at the large red connector that looks like the one you shorted at the S.A.M. if there's no voltage, it is blown. Good luck!
