Headlight Malfunction

So I was driving on Friday night and had all my front lights on-driving, headlights and fog-since the weather was crummy and I was on a dark, somewhat rural route.

I decided to turn on my highbeams after I saw some turkeys on the side of the road and when I tried to use the stalk that controls them and my directionals, I got a nasty surprise-it turned all the lights off.

I got to my destination and tried again-it did that again, then they turned on, then they didn't do anything, then the highbeams turned on with no input from me. It was raining, if that matters.

Now the switch just turns the lights off. None of the other stuff happened again. Where do I start, what do I troubleshoot, and should I be planning to take off the steering wheel to look at the cluster switch there?

Directionals are on same stalk and working fine with the usual up/down movement. High beams use forward to flick quickly (that never worked) and backwards to turn on (worked fine til Friday.)

Thanks. It's a 1995 E300 Diesel, in case I forgot to say that.

I have the same car. Twice the "light horn" (high beam flasher) part of the switch has failed in my car. The failure was mechanical—a plastic part inside the switch assembly snapped off. Since then I have been more conservative about using the "light horn."

You may have had a similar failure in your switch. Replacement of the assembly appears to be the only fix available. You can remove the steering wheel and then the contact spiral to access and remove the switch but I don't think you'll find anything you can repair.

I managed to make both of my replacements with parts from the local "Pick-n-Pull" auto recycling yard; new parts are probably $100-200.
