I've spent half an hour under the dash. I can't see it. Unfortunatley the flasher is dead. I can't turn my signal light on to find it. Maybe someone with a 57 can listen for the location??? Thanks again in advance.
No, it worked until a couple of months ago. First one side died, then the other. Not lying on the floor, so I assume it's still plugged in
If you were sitting in the drivers seat it should be to your left within 6"-8" of the steering column under the dash,trace the wiring from the headlight switch under the dash that should lead you to it.
Success! Turn signals now work again. I remembered I had a spare gauge package lying around. The flasher clips into the bracket upper left from the speedo.Much easier once you know where your looking. I hope this helps someone else. Thanks.
