I think blinking means it senses something there, but not enough weight to activate the airbag. Mine blinks when you put a heavy backpack there...
After installing my wet okole seat covers on my passenger side, my passenger seat belt light keeps blinking. Is there a sensor that possibly tightening the seat covers down might trip it thinking there is a person sitting in the seat? I don't remember it blinking before without the covers when no one was sitting in it, any advice would be appreciated!
