My air bag light goes on throughout the drive. Is it necessary to get it fixed?
on 2008 Chrysler PT Cruiser

My concern is that the air bags won't come on if they need to,

If the SRS/Airbag light is on there is a fault in the airbag system and they won't deploy in an accident. A scan tool is needed to retrieve codes stored in the computer of your car, These codes will indicate where the problem is .
Where do I need to take it to do this? Dealership? Is it expensive. I love my pt cruiser and it only has these minor mishaps that I would really like to take of but unfortunately money is tight right now so I want to get an idea of what I am looking at.
