Hello guys and gals, I've got a 2010 cobalt that has sat for roughly the last 2 years due to a blown engine. Just got it back from the shop and the service air bag light is on, but it was not before going in. I've seen a few posts saying that it could be a loose wire under the passenger seat, but the seat hasn't moved. Could the problem of been caused by the shop during the engine replacement? If not, are there any other probable causes?
