Turn signal flasher - PeachParts Mercedes-Benz Forum

Hello! I currently have the dash apart to put another radio in my 300D, and decided to replace the turn signal/hazard flasher (the old one still works but is real quiet; I can't hear it with the engine running unless the ashtray's removed, and then only barely; so I'm guessing it'll fail before too long as I've been told on here that it's supposed to be loud). I looked on Fastlane, and the part they describe as it (I think; they call it an "impulse relay") is slightly different. I believe mine has 3 pins and one plastic alignment dowel; however, the one that Fastlane pictures has 4 pins and that dowel.

Is Fastlane's part an updated one, or what's up? AFAIK, the flasher that's in the car now is original; the part has a "Made in West Germany" sticker or something to that effect. I brough thte flasher into the parts shop at the dealer and they want $50 for it. Fastlane wants $26 for the part I described.

Thanks in advance!

If it's ~$50 from the dealer and kinda under the ashtray, its the right part.

try doing a search on the part number itself through fastlane, or partshop. The number should be on your flasher.

Anyway, be aware that the MB flashers are considerably more complicated than the cheapo thermal flashers that some "nameless" cars use and they sell at generic parts stores.

Hey Warden,

For whatever it's worth, I too had a faulty flasher in my wagon (a 4 pin) and changed it out with a flasher (3 pin) from my son's 240D that's currently parked.

I don't know what the difference is, but I've had it in use now for two weeks and no problems yet.

The part number for my four pin flasher is: 0008211063 - this is out of the 1982 300TD. I didn't catch the part number on the 3 pin flasher, sorry.

where exactly is this relay located as i am trying to fix my turn signals and have narrowed it down to this relay

Theres the red emergency flasher switch then theres another relay under the console and fwd if the shifter. At least on the "later" 123s.

Be sure that it's not the red emergency flasher switch, when it's in the off position the turn signals work, if it's part way in between or in the flasher position, the turn signals don't work.
I thought I had a bad flasher, bought one, put it in and nothing happened. It turned out that one of the plastic levers on the emergency switch was broken and it wasn't moving even though the rocker switch seemed to be working.

Hi, I was wondering if you ever managed to find your flasher, and resolve your problem. I note you've got the dvd, but you don't say if you've had success or not. My own 240D by date should have a separate switch for the hazards, and a flasher, apparently, but actually has the 78-80 combined hazard switch with the flasher relay built in, which is also apparently not to be found for love nor money. I have had decades of experience with Harleys supposedly being altered on specific dates of specific years, yet finding frequent supposedly obsolete parts still being used in production until they run out, and occasionally doing very odd things, such as changing the bolt patterns of the cylinder base and the head bolts three years in a row, and finding an engine with one cylinder base pattern, with another year head bolt pattern, making the engine singular and unique in its own special way, and making repairs a matter of finding very hard to find cylinders which only were made one year.
I'm wondering if your turn signal flasher is built into the hazard switch assembly, as mine is, and was wondering if your dvd gives you any information which might help you resolve the issue.

yeah, any luck with that? I'm having the same issue now with my '77 300D. I have the combined flasher/hazard switch, MB part # 123 820 02 05. Buzzes loudly when I turn it on. all 4 indicators turn on but do no flash. Turn signals light up, but do not flash.

Can't find the dang thing anywhere; even in a jnkyard

Hi Warden, old models must have had three pins as there is a statement under the ID on the Worldpac about "newer modules have 4 pins. please verify the plug has an empty hole where the forth pin goes etc."

well I bought a new replacement when the original flasher stopped completely in my '83 (now sold) and the new one was much quieter than the old one. FYI.
If you need some more noise to indicate the turn sigs are working you could buy a small buzzer and wire it to the lead that carries power to the tail lights, just an idea. They probably sell one at Frys on Portage St. in PA.

my 240D 1981, USA version, has it between stick shift of the automatic gearbox and the ashtray, under the small removable little panel around the stick shift. You have to lift it up and remove it.
now, my flasher failed and the MBenz was quite expensive (in this country) So I bought a japanese for a fraction of the cost $5.00 I believe was for a toyota (they show the electric diagram on it) with 3 pins. I installed 3 "extension wires" connect it and worked ok, and that was about 6 months ago. no problem I works as if it were the original. Hope this idea helps you. Good luck
