Answer
Tracy,

Wow, I have never heard of such a problem with the turn signal backfeeding through the seat belt audible warning system.  I would be looking to see if someone has modified the wiring harness or if a ground has come loose on the belt system and the turn signal system.  Since I have not heard of this there will be the need to start back probing the circuits.  I would check to see that the seat belt system is in working order first.  No indicators or beeping when you are belted in.  Are the bulbs on the left side working properly.  None are burnt out?  That could cause the current to find another path.  It has to be something simple but I have never heard of it.  I would have to do the back probing to find the problem and what I have described above.
