The seat belt warning chime on my 1999 Elantra rings sporadically but
very often when I DO have my seat belt on. It is extremely annoying.

Intermitent electrical issues are the hardest things to diagnose and my
dealership can't fix it.

Does anyone know how to disable this or at least muffle the sound?

I always buckle up so please don't reply that I need this warning chime
for safety. Driving with this chime constantly going off is the biggest
danger as my stress level goes up!
