My turn signal relay is buzzing

[GloriaRedStang]

And I mean buzzing loudly, like an alarm!

I have a 1984 n/a. Anybody have an explanation and/or fix for a buzzing turn signal relay under the dash? It sounds when ignition is off and turn signal lever is centered (not signaling left or right turn). If I turn key one click in (power on but no ignition), the buzzing stops. If the engine is on, the buzzing is off.

If I pull out the relay, obviously, it stops. Other conditions: my dash blinker is out, but it's been out longer than the buzzing, which just started yesterday.

Is this something that replacing the relay will solve? Or cleaning a ground or replacing a fuse?

I don't know how to chase a short, but if that's it, can somebody point me to the likely culprits/locations?

This might cause me to fail my overdue safety check. Thanks in advance.

I have the same problem, does anyone have a solution for this??

Relay buzzing is caused by age and wear on the relay- as the contacts become worn the coils begin vibrate as the sets of contacts are sitting uneven. Occasionally this symptom can be caused by under-powering the coil, perhaps due to dirty points, but the former is much more common. Replacing the relay should do the trick.

Thanks but, have tried several relays, wont fix the problem.

Do you have access to a meter? What is the voltage supplying the coil while it is buzzing?

I would suppose some stray current is grounding through the relay. Try pulling fuses one at a time and see which ones affect the buzzing, then look for a reason why those circuits are connected. Maybe something like the turn signal switch is involved (headlights?)

Has the headlight bulb wattage been increased?
