my turn signals are not working on my 1984 mercedes 300td wagon. the bulbs are good and the fuse is good. but when i turn on the signal(right or left) i get nothing. can someone please tell me what may be wrong and where to look. they quit working all of a sudden.
thank you for any help all the lights work but the turn signals

Sounds like your indicator relay box has failed or has come loose
Need to find out the location with your hand book wiring diagram(Vehicle makers put them in all sorts of places)Plug in to replace
Price to replace is cheap. But get it from a Motor shop not a Mercedes dealer and save yourself paying double prices
BTW Are your Hazard flashers working? this is a different relay, but uses most of the same wiring as your direction indicators (if it was a wiring problem these will not be working also )

the hazard lights are not working either
everything was working yesterday and today no hazard or turn signals. any suggestions

The turn relay retails at $32
There is a chance that the relays are both ok and the fault lies in the turn switch itself This is about $55 to replace
But get a knowledgeable friend to help you check this out, the possiblity is good that this has gone Kaput
Go to a car breakers and get 1 off a scrapper for about $5 together with the turn relay box (remove them yourself )

do you know where the indicator relay box is or how i can find it. i don't have an owners manual for and i can't find a free wiring diagram on the web. thank you so much for your help. you are always so helpful.

No offense bedstor, but check the fuses first.

The poster says they have checked that and they are intact unless... they have a high amp fuse in the slot Should be about a 10 or 15 amp fuse at most, will be marked on the fusebox cover

thank you bedstor. with the information that you gave me, i was able to eliminate several possibilities. i found another site, like this one but it is just auto repair(bentley publishers) and some one had the wiring diagram plus has had the same problem on his car. he told me to check the solder on the hazard switch in the console. as soon as i moved it, the flashers started working and the turn signals. thank you so much for all your help. you are always a tremendous help. thank you again

I have the same problem with my merc. can you direct me to the same diagram you got or at least where the problem was fixed by you and how? I found the parts and Dont know what to do next. My hazards work and my blinkers do not.

Thanx

Without the Workshop book Both of these items are hard to Locate
However....Since the Topic was made This forum Posting tells you where to look for both of these I think you'll need a "small hand" (Have you a child?) or grab, to pull out the Indicator relay behind the ashtray and you'll have to match the type # on the casing
