All turn signals lit when lights are on
1984 w123 300d turbo
Everything works fine, until I turn the headlights or parking lights on. Once they're on, the turn signals all stay solidly lit. I'm guessing it's a relay, but i've found two in the circuit. One in front of the shifter, and one under the hood. Am I on the right track? |

The flasher relay is the one in front of the shifter. Also check the hazard switch in the center console.

Thanks for the quick reply.
I thought that would be the correct relay too, but when using the signals I noticed there was another ticking under the hood. I'm still leasrning this car ![]() Visually both look excellent, and i've tried "exercising" the switch. Would you guess the flasher relay is the issue? |

What was ticking under the hood?

On top of the driver side wheel well there was a black box with a couple silver relays inside. One of those also ticks when the signals are operating normally (headlights off), although much quieter than the one inside.

Those are for the A/C compressor and electric fan. They have no relation to the lights.

Never spill Pepsi on your emergency flasher!
I did, and had similar symptoms till it dried out. I attempted to take it apart to clean it, but it asploded
![]() Bought new, used one off Ebay and everything normal since.

Wow, that must have been a heck of a spill to get into the flasher. That makes me feel a little better though.. Those relays are expensive.
I've only had the car for 3 days, maybe the PO spilled something.

I ordered a flasher, and the hazard switch. My luck, it'll end up being wiring, lol.

Relay and switch replaced, yet the problem remains. Where do I go from here?
