I have a '02 Sebring Convertible Limited and the airbag warning light has come on. Dealer says it's the "Driver's side seat belt tensioner sensor" that is the cause and he needs to replace the ENTIRE seat belt assembly at a cost of 0. He says it may cause the airbags not to deploy in case of an accident... Is there a cheaper way to fix this?? I have to replace a whole assembly because a sensor is broken? I really do not need to spend that money right now (especially since I just had to pay 0 to replace a plastic valve housing that had cracked and caused coolant to leak)... Thanks for any input! Yves
