Mister

[Bulelani]

I need help for my mercedes-benz w203, It doesn't indicate, horn not working, wipers don't work, electric windows don't work. Headlights go on when switching engine on, and bright light icon shows on dashboard even if the engine is off. Sunroof works very well, internal lights work well as well. What could be the problem?

I am glad the sunroof works. At least you can enjoy the nice weather we are having.

I would get it on star to have the codes read. Have you looked for water in the boot and under the carpets ?

SAM failure (can't remember whether front or rear) can cause all sorts of electrical funnies on the W203.

Aye sounds like SAM confusion.
1st try to look to see if moisture has got into the multi light switch. That screwed mine when it did, the windscreen needed removing and resealing.

No I didn't and I bought the car from auction sale with these mulfunctioning things.

Hi M80, I don't even know what SAM is and where it located in the car.

I am only here because I was curious about the thread title...and I am still none the wiser.

Mebees it was meant to be misteri.

But my ynstynkt is that if Bulelani doesn't get a pro in, then the problems will only become more complicated. I've never removed a SAM from a 203, but if it's anything like the 639 it isn't for the aint farted.
But if the windscreen is peeing on the multi switch then the SAM aint the issue, it has merely confusing signals going to it.
