Another Turn Signal Question

[Chally]

Turn signals stopped working today after many years of trouble free operation. Four-way flashers, brake lights, everything else works. With key on I’ve got 12v on both sides of the radio fuse, 12v coming into the red feed wire at the turn signal switch harness. I couldn’t test the radio harness as it is not accessible, but I’ve got an aftermarket radio and am not using the radio connector. I jumped 12v across the red terminals on the two plugs and I am getting 12v out to the two green wires and two brown wires when activating the switch.

Am I missing anything here before I swap out the flasher on the ash tray? It does not appear to be easily accessed without taking dash trim off?

If you haven't altered the wiring, and if it was working fine for a length of time, prior to failure, my guess is the flasher relay. They ARE a mechanical relay 50 years old, or so. The turn signal switch in the steering column, would not typically fail in both directions.

If I put my head on the passenger floor, and look up, I can see the turn signal flasher relay on the side of the ash tray. It's very light weight, and only held there by the clamp with friction. Just give it a tug, maybe a firm one. Or, lift it out along with the bracket. Note in the image, the bracket as a little tab behind it.
