The tune is played by relay #4 that plugs in at the top of the fuse panel.
Mine's a '90 so is likely what you have.  You'll have to loosen the panel and,
in mine, #4 causes it to take a bit of maneuvering to remove the panel.  This
relay also has a "grill" on its top to allow the sweet song to escape.  If it's
there, your problem is electrical.  If it's not and you want it, you need pn 321
919 433 B.
