is your headlight warning and key reminder warning working properly?

and with the key in run without the engine running do you still have the buzzzzzzzzz

I disconnected the speakers and the blower motor too! I'm stumped!

I know it's a stretch but speakers have coils in them and maybe interference from the coil is still affecting them? Pain in the *ss to remove speakers so I'd keep looking elsewhere. Can you make us a longer video of the sound. Get some revs in. Put the camera by the floor inside and also under the hood near the firewall? I'm invested in this one.

The chime is working okay! And no buzz with key in not running.

I’ll try to get under this dash tomorrow.

I’ll try to get another vid tomorrow. Buzz is consistent, doesn’t change with revs.

Sounds like an amplifier buzzing or humming.

Is it possible that you have a buzzer for your key to tell you if you haven't removed it from the switch once you turn the car off and go to leave it that has shorted out?
