Seat belt light

The seat belt light in my 1999 Chevy Prizm stays on blinking all the time, when the ignition is on. According to the owner manual it should go off after I tighten my seat belt. What could cause this problem?. I already checked the seat belt lite fuse, and it is OK. Will appreciate your answer.

Check under the seat for a connector that came loose.

If you have anything on the seat with some weight to it, the light could come on.
