I had a Service Air Bag reading and light on the 98 Deville, took it to a stealer / Dealer, he replaced the sdm, didnt fix it, then he replaced the battery cable, didnt fix it , the 3 rd time in he said he thought it had a short but wasent sure,so I fixed the damn thing my self with a pair of senser from a 97 Deville, as this was a recall item I wonder if GM will want to pay for the actual repair and the chasing of it ?
