Buzzing noise from under dash

1995 f350 XL. After a month of owning truck, it's making a buzzing under dash when I start the truck. Last 2-3 seconds.

Any ideas? Is this an indicator of some sort or is that a noise the equivalent of "key in ignition" warning chime?

I think it's the seat belt buzzer.

You know what's funny is that it started 2 days ago. Which is when I first decided to use the seat belt. Coincidence?

You can remove the buzzer without effecting anything. It won't warn you if you leave the keys in the ignition, or the headlights on though.

You may have scraped some rust off or something when you used your seat belt. Who knows?
Every once in a great while, mine will work for a bit then stop again. I don't even worry about it, these trucks have so many odd gremlins, it'll kill you worrying about why something decides to work then doesn't.

Constant buzzing sound from under the dash

I just got a 2001 F-350 with the lights switched over to LED.
I have a constant buzzing sound from under the dash. it will keep doing this even though it is not running.
The only thing that shuts it up is using the turn signals.
Any suggestions for fixing it
