Re: [MBZ] errant buzzer
A couple of weeks ago my '81 SD started an occasional weak buzzer sound from under the dash. It was rare and brief at first, and stopped when the blinkers were activated. It has gotten more frequent and longer lasting, and this morning when I turned the key the left blinker came on and would not quit. A bit of fooling with the turn switch got it to go back to an occasional buzz, but I suspect things need to be dealt with. I pulled the knee panel and determined that it was the left buzzer that was letting go. My suspicion is the I am getting a short in the steering column and need to pull the blinker stalk and check that. For those familiar with such things, I could hope it is something that sounds easier. Any other suggestions? As has been mentioned before, first potential culprit is dirty contacts inside the hazard switch, second is a bad battery or contacts to same, and third would be a bad blinker itself. Note that my experience with our 560 SL and my attempt to make a louder clacker for top-off driving indicates that a slight load on the blinker itself (such as a dirty switch that has some conductivity when it shouldn't, or a badly-placed extra relay there for noise purposes) results in a weird muted buzzing. That'd be my fourth suspect. -- Jim
Re: [MBZ] errant buzzer
The battery is about a year old, and has always been strong. But as you mention it I noticed that for my second start this morning [first start was fine when I moved EM from the shed to the driveway to troubleshoot the blinker / buzzer] it cranked very slowly for a few turns - longer than it has ever taken start. Turned the key off and on and it started right up as usual. I'll have the battery checked also.

Re: [MBZ] errant buzzer
I will give that a try, along with a few shots of contact cleaner. That does sound much simpler than a disassembly!

Try operating the hazard switch half a dozen times and see if thing return to normal.
