My seat belt chime on the passenger side has stopped working. When I took the car in to the dealer to fix under the warranty, they said that there was no passenger side chime. Mine has always chimed when something heavy or someone sat in the seat without fastening the seatbelt. They didn't even check it out they just said there wasn't one.

 

There's no chime for the passenger seat that I'm aware of. Just the driver seat. The sensor in the passenger seat is just for the air bag on/off.
