W115 1972 220d turn signal issues, and other electical questions.
So some issues with my recently aquired /8
When I picked up the car, the drivers turn signal was stuck on...I pulled the flasher/hazard relay apart, noticed that the board was sitting outside of the guide, and that it was likely causing some sort of issue. I took it apart, and reinforced the guide areas with superglue, and re-purposed zip-ties. Ghetto I know. It doesn't seem to have worked. Now when I plugged the relay back in, the right turn signal was not working at all. However, if I push the harness into the relay harder, the turn signal comes on...leading me to believe that I fixed nothing, which is ok, but I need an idea of what to do to fix it. I also took, the multiswitch off and took it mostly apart, and did not see any issues, so at this point, I do not know if it is in the switch, or in the relay/flasher. I am pretty sure it is either in the flasher, or in the wiring between the flasher, and the multiswitch. I am considering seperating the turn signal from the hazard flasher, but I don't understand how the electronics work on this car. I do not know if the turn signals have to be wired into the hazard relay in order for the hazards to work. If someone has the turn signal wiring diagram for a 1972 220d that may help me sort out, what I can and can't do, and what troubleshooting I can do. I also have several wires, in various places that are connected to nothing. I will post the pictures and hopefully we can shed some light on some things. Some of the wires are near the a/c compressor. And there is evidence that atleast one of them connects to the casing. The other wires are under the dash/in the center console, and I am pretty sure are all related to the radio. And the last wire is a blue one, coming from the gauge cluster... My air conditioning doesn't work, I can't even figure out how to turn the blower motor on. Thank you all in advance. Ron |

I will report back here, to myself when I figure this all out. Maybe it will be of help to someone else down the line.

If you feel like checking to see if the same (or a compatible) part was used in a 1975 240d (for which I can get the VIN if needed), I can check to see if I still have the hazard switch from my part out. There's only one guy I know that could have possibly bought it from me. Otherwise, I still have it.

Hey fonzi, I will look into it, but I am quite sure that those cars used a flasher under the dash, and the hazard flasher was on a completely different circuit.

A good fellow on here named Scott has sent me 2 flashers to test out, I will be testing them today, or tomorrow.
Still no clue's on the other stuff, though I have not fussed much with it. I will wait till the car is on the road, to do any real life diagnostics with the air conditioning. I am not starting the car right now, so I don't want to kill the battery in attempts to sort these issues out. |

A "new" flasher relay solved my problem!
