Headlight Switch, replaced then...

[Bluebird]

This is the second switch NAPA/Echlin part #HL6548 in 35,522 miles. The switch was getting warm, the headlights would not turn on unless I moved the wires into the switch. The switch had melting below/inside spade-H. The female connector with the Green wire in the box, melted the box walls around the connector. I put a plastic shield on the female connector. I taped some exposed Green wire above the box. All works well, no heat on the switch when on. However, when I push lights off/in, it triggers a buzzer for just a moment, then the buzzer stops. What do you think that buzzer is about

There is no buzzer/warning if I leave the lights on, remove the key and shut the door. I hope I explained with enough detail :-laf.



Thanks in advance , Patrick.
