Turn Signals and headlights not working
Still can't figure this one out.
So the hi beams do work (All fuses look good too). The hazards do not work, the headlights do not work, and the turn signals do not work... but the windshield wipers do work. i have replaced the flasher relay under the wooden piece by the shifter.. still nothing.. i have also replaced the hazards switch (red switch). Is this most likely combination switch? Any thoughts on what to try next. 1984 300TD Thanks! Last edited by ambush276; 02-23-2019 at 03:52 PM. |

You say fuses are good..did you actually take them out and look at them? I'd go ahead and replace all of them just to be sure, it's easy and if you haven't done this already, it'll need to be done.
I'm pretty sure they're all on the same circuit. |

Quite often on the 1937 Fleezer-Noodle sedans this is caused by either the Dysbumtion Polar by-pass or the erudication relay. The best results are obtained by adding approximately 3 liters of distilled urine into the compactic chamber reservoir.

In other words, model and year of the vehicle in question would be helpful.

Given that year, check your emergency flasher switch on the console. A lot of the lighting functions are controlled through that switch.
Make sure it is plugged in. If so, they can be disassembled and cleaned or replaced. A hint to their function is how deceptively pricey they are. |

Double check all your ground connections from the lights to the chassis. Bad ground connections can cause all sorts of electrical maladies.

are there specific ground points that usually go bad? any ones to particularly look out for?
I am sure there is a diagram on this forum showing all the ground connections.... somewhere |

Heavy braided cooper cable from starter to solenoid possibly contacting the starter case?
This happened to 'Stormcloud' and caused a no start, no headlight issue. http://www.peachparts.com/shopforum/3790371-post1.html

I'm no electrician, but....
You said high beams work but not low beams. Just wondering if your low beam bulbs are burned out and somehow affecting the turn signals. Replace the bulbs and see what happens. At least maybe your headlights will work again.

Do the W123 have a lighting relay? If so, can that be bad?

I've come across a lighting issue similar to this lately. It was slight corrosion on the fuses. The low beams and high beams are on literally 4 separate fuses. Aluminum fuses are notorious for problems like this.
