I too have the airbag light on. I counted the flashes and it is code 33.

Air bag light blinks and then stays on. Blinks appear to be 33
Just noticed it, no fix to date.
air bag light on. ford replaced driver side seat belt and then the light came on again and ford said the passenger side seat belt also had to be replaced. I refused the repair and since the seat belt works ok will forget about the air bag if it depends on a buckle spring. Have driven for over 70 years and have never had a head on collision. Have only a few more years left to drive.

I had a problem with my air bag light on the instrument panel staying on all the time. I went to my garage and they had to replace both the right and left side belts. My car only has 30,000 miles on it and it does not seem as if this should have occurred for this short time.

2 of my 2005 Grand Marquis' seat belt buckles have failed.
Ford dealer wants $672+ to replace driver side seatbelt. I refused the fix. Hopefully airbag will still go off if car is in an accident (especially if someone is in passenger seat). I think this should be a recall issue especially since there is no reason to believe that if fixed the other seatbelt might have same problem.

Air bag light on, some beaping. Dealer says it's the seat belt assembly, will cost about, $500.00 to fix.
