driving to work this AM, noticed my airbag light flashing.

Nothing has been changed on the car at all, completely stock as far as electronics goes...

22k miles on my car....


Any ideas? I just went to lunch and started my car like 3 times to see if it would quit but it still just blinks. Called Nissan, they dont have any ideas w/out taking it in and looking at it.

Any Ideas or input would be appreciated ?????
