... well, to begin with, the behavior you describe for the idiot lights with
the fuse in place sounds correct to me.  

I don't think that there are many things that can buzz in the IC of an '83
urq beside the flasher relay.  I have a similar situation on my '85 4kSQ ...
for some reason every once in a while the flasher relay buzzed.  I tried
other modules to no avail.  I'm pretty sure I have figured the problem out,
but I haven't had an opportunity to confirm it yet.  I'm pretty sure the
problem has to do with the emergency flasher switch ... that there is a poor
contact in there that is causing the buzzing.  I'd recommend that you try
actuating the emergency flashers a few times to see if it doesn't resolve
the problem.  

HTH!
