Most likely more of the dash needs to come apart, this is most likely a relay or module making this buzz sound.

It would be impossible to say which one it could be at this point due to how many of them there are back there.

Once you get more of the inside of the dash exposed, it may be easier for you to isolate which one it is just by touching around there.

Thanks, Ron
