I have a very intermittent buzz coming from the fuse box area on my 86
Syncro.  It seems that it's totally random and doesn't seem to have any ill
effects.  I know that relays are in that area and that is what it sounds like
a stuck relay or one that's trying to do something.  The buzz lasts from 1/2
to 2 seconds and doesn't seem to be related to any particular function or
driving situation.  I can't reproduce it so its very hard to check which
relay it is.  Anybody had any experience with this.

Thanks Blitz
