Hi all --

I did a search but did not find a conclusive answer to my problem.

The Symptoms
Just today in my 1999 W202 (C43), my turn signals (left and right) did not come on when I moved the stalk to indicate a turn. At the same time, neither the winshield wipers nor the winshield washer fluid came on when I turned or pushed the control stalk. I also tried the horn and it did not work. Strangely, when I pulled the light switch out to turn on the fog lights, neither they nor the led in the center of the light switch came on. However, the highbeams and the blue indicator light on the gauge panel did work.

About 30 minutes later the turn signals and winshield washers started working normally again, I didn't try the horn, and the fog lights came on but the led in the center of the light switch did not come on.

What could be the problem? I truely need help with this one.

Previous posts here and a Club202.com indicated that this problem may be caused by a faulty voltage regulator (on back of alternator), a bad wiring harness or a bad master relay. None of those posts gave the final solution to or the exact cause of the problem.

Any help would be appreciated.

Thanks,
