A few yrs ago, my airbag light came on one random very cold day. Next time the dealer saw it, he reset and said the airbag was fine.

I have always been able to reset this light come inspection time via the - turn key/push door sensor/close door/start engine routine - and have done it like 10 times in the last few yrs - I was even able to do it a few weeks ago- but it has come back on and now appears that it will not reset to non-blink mode.

Has anyone else ever come across this problem or offer any advice other than to take it to the dealer?
