Turn signal issues
Hi friends,
I search the W124 boards for blinker or turn signal issues, and was unable to find anything that remotely describes the issue I'm facing.
For the funny folks, I did check for blinker fluid
The issue is as follows with my 1994 E320:
When I turn my car on, I drive off, and turn signals work fine. Usually after using the turn signal stalk a few times, for turning or changing lanes, the turn signals stop working. No light on dash, and no blinker sound, nothing. Both sides, the same. If I move stalk down to turn left, or move stalk up to turn right, the turn signal system is dead.
Interesting thing is that after a while it comes back, and turn signal system works again. And eventually stops working. So it goes off an on like that, between working and not working.
I own an Audi, where there is a known issue with the turn signal relay, when it goes bad, it basically makes the turn signal behave similarly as described. However, with the Benz, I have not checked if the hazards work when the turn signals are not.
Has anyone experienced this issue? I am ready to bring it to the dealership for troubleshooting, however if I know what needs to be done, I can simply do the work myself, depending on difficulty level.
Thanks for any assistance.

I had the same problem om my '94 E320 couple of years ago, except the hazard flasher would also quit along with the turn signals. In my case it was cold soldering inside the turn signal relay. The relay is located inside the fuse panel under the hood, you would have to take the top of the panel off. There are few relays in there, I took the top of the panel off while the turn signal was clicking, it allowed me to locate the right relay. I then pulled it out and took it apart. While carefully instecting all the slodering joints I quickly found the hairline crack in one of them. After re-soldering the connection the problem was fixed.
Hope it helps.

struck out on the fuse
I checked the fuse, and it looks good, and soldering on the connector good as well. Even tried a different fuse.
The issue appeared again, and I tried the horn, which both seem to be tied to fuse number 6, however turn signals did not work, yet the horn was fine.
Must continue to check. Probably going to the dealer to get it looked at. No turn signals is a dangerous thing.

Hi,Kirin,
I think your fault is probably a short circuit inside the combination switch on the steering column, the only way you can check this is by fitting another switch which is known to work properly.
Cheers, Geo.

I don't think you read my earlier reply. If the horn works and it is on the same fuse with the turn signal, it is even more likely that you have the turn signal relay problem.

Update
Thanks Arnie for the feedback. In the Audi that I have the hazard relay is actually behind the hazard button, thus in attempting to compare the issue between Audi and Benz, I may have mis-understood.
Well, I was unable to find any crack on the soldering as Arnie had mentioned. Decided to take the car to the dealership for a quick look. They did replace a relay (part number 201-821-01-47). Unsure exactly where this relay was replaced at. Must check the fuse box again.
So far all is working, given it was a $161 part.

Not sure if the lectrics on the 320 and 420 are simular but I had problem with the turn sigs and wiper !! I located the wiper relay and it seems there is some kind of weak contact where the relay plugs in. When I pushed down on the relay both the wipers and turn sigs worked! I made me a small cardbaord block to lay on top of the relay and when I snapped down the lid to the box it help push it down in place! Been like that for more than a year now! Also you may want to get some contact cleaner and snap off that little panel by the stalk and shoot some contact cleaner up into the switch. Things might just be dirty!!

Hi friends,
The issue is as follows with my 1994 E320:
When I turn my car on, I drive off, and turn signals work fine. Usually after using the turn signal stalk a few times, for turning or changing lanes, the turn signals stop working. No light on dash, and no blinker sound, nothing. Both sides, the same. If I move stalk down to turn left, or move stalk up to turn right, the turn signal system is dead.
Interesting thing is that after a while it comes back, and turn signal system works again. And eventually stops working. So it goes off an on like that, between working and not working.

I've got the same problem. The signal usually fails when I need to cross 5 lanes of traffic to reach an exit. I've noticed that the Rear Defroster and Hazard are also affected. Hopefully I can use the info in this thread as a starting point for my Mechanic and I to fix this EXTREMELY frustrating problem.

Blinker/ Hazzard inoperable
hi ! I am having the same exact issue and gonna try Arnie's thread on fixing this problem. But first, it stated awhile ago and worked fine then it stopped working and cane back working fine after a year until now it just stopped working. I noticed the front passenger parking lite worked except when on - only the signal and flasher worked not the parking light. And now this blinker/ hazard not working but like Arnie, the horn works.

1993 W124 E200 Diesel
Hi Guys
I'm a newbie here.
I drive a 1993 W124 E200 diesel. Today on my way to work, I noticed my turn signals had stopped working. I checked the hazards, wipers headlight flasher/dimmer they all work fine. Only the turn signals aren't working. I drove it 2 days ago and everything was fine.
Is it the combination relay or some other issue?
Hoping your collective wisdom would help me out here.
Thanks

Kavin if your hazard lights work you can rule out the flasher unit .It could be the arm on the steering column for flasher and dipped beam .Just inspect all the fuses first in the fuse box .But its looking like the flasher arm switch is faulty I am sure its a faulty fuse in the fusebox
