All of a sudden both of 01 LS430 horns are not honking. The owners manula says there's only one 10A fuse in slot 82. Of course, I checked the fuse and put another in just to be sure, but nothing. It certainly appears to be an electrical issue. Is there another fuse somewhere? Taking it in to Lexus is my absolute last resort as they will charge me a gazillion $$$ even if it's just a fuse, and come up with another gazillion in 'recommended other repairs'.

Thanks
