idiot lights
 

Interesting occurance!

When turning on the turn signal, ALL of the idiot lights blink on for a second, then go off. Only happens periodically. Any ideas? Car is a 91 300SL.

Thanks! Jim

this thing happened to me when i changed the turn signal bulb and bymistake the dealer gave me only one fillament bulb as soon as i changed teh bulb this problem went away check it might help
otherwise just wait for soem one else to help u
hope u ll find this problem soon i know how it is to be in a situation like this

Hi Jim, it sounds like the circuit board on your instrument cluster is fried. This was a common problem on early 129's and 140's.
