As you may know, the buzzer module in question here contains the
logic / timer circuit for the seatbelt light / door / keyswitch as
well as the actual noisemaker. A fault in the electronic portion
could also cause the problem described.
[related anecdote]
When my (then daily driver) Spit was just a couple of years old;
This buzzer started coming on randomly, at a lower than "normal"
volume, particularly during damp weather. It was less annoying than
the usual sound it used to make and you couldn't really hear it at
all (over the Monza exhaust) at highway speed. I had decided to be
the DPO that Atwell mentioned and disconnect it none the less.
The buzzer module sensed this, and changed it's behavior to a
continuous mournful moaning kind of sound. This went on for about
3 days non-stop then it unceremoniously expired. A buzz gone, but
not forgotten.
