seat belt light

I just bought a 97 grand am, and the seat belt light stays on constance, I plug in all the seat belts and thats do'nt work, I've unplug the wires under both seats, still on, anyone have any ideas? thanks

Wires under both seats? Do you have power seats? The only buckle tied into the seat belt warning is the driver's buckle. It is usually a single wire plugged into the bottom of the buckle srap where it bolts into the floor. You can determine if it is just a poor connection in the buckle itself by unpluging that one wire from the base of the belt and ground it out to the chassis. If it is just a poor connection in the buckle, the light will go out once that wire sees ground. If this is the problem, use a good aerosol contact cleaner and spray the inside of the buckle for a few seconds then work the latch plate in and out of the buckle a few times. This will hopefully fix you woes. Good luck.
