First post on seat buckle made me curious... just tried it and plugging in the seat belt will get rid of the seat belt chime but does nothing for the door chime when it's open...go to a junk yard and get a seat belt insert. put it in the buckle. I also saw some "redneck version for sale online somewhere. LOL

Annoying Seat Belt Chime Fix
When you open the driver side door the latch that's attached to the door handle on the inside of the door take your finger and push it all the way back and the beeping noise will go away. To get latch to go back in place just pull the door handle open.Anyone attempted this? It drives me nuts when cleaning the interior.
