01 ford ranger air bag light

My air bag light keeps blinking on the dash and the passanger air bag is off right now. Just wondering what the issue could be and how to fix it. Thanks for any help

DO YOU HAVE ANYTHING HEAVY ON THE PASSENGER SEAT, MY CAR DOES THAT CUZ IT HAS A SENSOR IN THE SEAT

No the passanger air bag is turned off at the dash. I think it is the driver side but it started blinking as I was driving down the road.
