Default Relay buzzing when door is opened

on my 71 there is a relay on the drivers side fender, under the hood, midway down that buzzes when the door is opened. It stops when unplugged and doesn't seem to affect anything, anyone know what this could be? I don't see components of a factory alarm.

Is your key in the ignition when this occurs?

Hi l455
This is the horn relay… is it what you're seeing?
It should 'buzz' when you open the door but only if the key is still in the ignition… as Paul asked.
Regards,
Alan

You may have to repair, adjust or replace the 'key warning buzzer' switch.

You can stop the noise temporally by removing the 'F' wire at the harmonica connection.

If the buzzer is going off.. the key warning switch in the steering column is more than likely the issue.

If you have tilt tele.. the switch is still available on a limited quantity. If you have a standard column, the contact switch is discontinued. http://willcoxcorvette.com/product_i...ducts_id=25484
