I need some help. I noticed the other evening that the "PASS AIR BAG" light on the over head panel (next to OnStar) stayed on. I looked it up in the owners Manuel, page 116, and it said it indicated a problem with the airbag system and to have it serviced immediately. I unhooked the battery and noticed it stopped staying on. I just brought it into the dealership to have it looked at and there were no codes for any airbag system. When I turn the car off, the light seems to stay on for about 30 min and then goes off. Can someone please let me know if their truck does the same thing? Any feedback would be great.
