Dash lights come on with a chime and go off

The chime is normally a small looking relay in the fuse panel assembly under the dash. Is your light coming off when you insert your buckle? If it does, your chime is bad and needs replaced if you want to hear it. Sorry I couldnt be more help, try buying a junkyard chime to test or if you have a volt tester check for power and ground circuits at the chime junction location. The chime like I said looks like a relay but has a tiny plastic speaker inside it.

disconnect that sucker from under the seat. Look under the seat ( move it all the way forward it will easier) find the seat belt buckle there will be a wire coming off it. follow the wire to the connection then disconnect it. no more chime. or light on the dash either

these chimes are in fact warning codes, these chimes are telling you there is a problem, It may be a connection problem in your seat belt warning system to a serious engine problem, your dealer will know just by the tune it plays but check your seat belt first and then the dash warning lights

there is a tiny little box under the driver side dash that makes the sound.
No easy way to tell you exactly where it is, but it's under there.

I suggest you check all the instrument panel grounds. You will need a factory wiring digrams fo rthis, so try and find a used factopry repair manual on eBay is my suggestion as fixya has no wiring dioragrams or repair manuals on file for this car

The belt buckle sensor might be unplugged under the seat. Or the wiring or switch it self may be broken.

Yes it should be under the left side of the dash above where your left foot would be. If you hear a bell when the key is in the switch with the door open, then the wire for the seatbelt may be cut.

Hi
There is a switch in the seat belt latch whe your sitting in the seat this will ba the part o the right side, see if something went into the latch part? or the switch is bad i think you have to replace the belt to fix the switch

If key is on locks go down and pop up. If key is off, locks stay locked

you could push some thing into the female end like an old blockbuster card or equivelent to depress the switch inside so it thinks your seat belt is on
