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?

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.

Thanks for the advice. I'll try and hunt down a relay and give it a go. I'll post back with the results.

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?
