Wife and son went shopping yesterday. Took his '95 Bonneville. Car looks and drives like new. They get in car after shopping. He starts car, and they get ready to head home. About 30 seconds after starting, car still in park, nobody around, passenger air bag goes off. Wife was bending over picking up her bottled tea from the floor. She got a bruised chin and light burns on face and neck. Lucky. Son was just stunned by the explosion. Passenger side windshield busted, and dash-wide trim piece along the windshield needs replacing. Guy is coming out tomorrow to replace the windshield, about $200. The kid will get a new trim piece at the boneyard. He keeps tools in the trunk and pulled the steering wheel bag right there before they came home. Didn't trust it any more. He thinks on that car both airbags should always go off together. He says the airbag light was coming on intermittently for a month or so until about half a year ago, then stopped when the bulb burned out.. You need a Tech 2 to pull the code, but he read that the airbag trouble default is "don't deploy," so he didn't worry about it. Now he's going to have to talk to the GM dealerships mechs near his work and get a Tech 2 read, because he fiance won't have it any other way. He would just pull the airbags if he had it his way. BTW, the GM shop manual only covers wiring schematics, and says to consult an "airbag professional" for everything airbag. Guess they keep that in-shop. Anyway, an airbag going off like this is pure bullshit. If he comes up with an answer from the GM mechs I'll follow up.
