High-Beam problem/gremlin
 

This one surprised me, but I guess it's the first of the electrical problems. It's on the 93 500SEL. I was driving down the highway last night and when I pushed the stalk forward to engage the high beams. The headlights went out, all of them. Pass to flash still worked though. And low beams still work fine. So it's not the bulbs. I could not replicate the problem in the driveway or with the car stopped. Then the problem went away...now it's back. Stock bulbs, nothing fancy. I couldn't tell if all the lights went out or just the low/high beams. What do you think? Thanks

Have seen the combination switch cause this problem.
