Thanks for the replies! Josh, I think you have hit on it. This vehicle had an aftermarket alarm which I removed, and this may have been a way to turn it off. Anyway, it does nothing now and the wiring behind it has been restored.

Is it actually a button or just a light. Usually the aftermarket alarms had a light that would blink in a visible location as a deterrent to make the thrives move on to another car. The button to defeat the alarm was usually mounted in an obscure location that only the owner knew as a backup, not in the most visible spot for a the if to shut it off.
If it's actually a button,, could have been a valet mode button that keeps the alarm from automatically setting and the light in it indicates it was in that mode, but that was usually a toggle switch, also hidden somewhere.
