Car's dash airbag light went on and stays on. Dealer has had the car for 10 days and can't find the problem. They have replaced sensors, modules, checked wiring, ... Nothing. The computer cannot communicate with the airbag module either. The poor service guy is pulling his hair out on this one. Everything he tries makes no difference. I want my PT Cruiser back and Chrysler has been no help in resolving this issue. Any ideas from this end?
