    While there can be answers given by searching forums, they are just as often misleading because every car doesn't experience the exact same failures. The airbag light could be on because of a fault in the airbag system, and it could be on because the instrument cluster isn't able to communicate with the airbag module on the data bus. (Hence the suggestion of the lost ground) In practice this set of symptoms can occur because of problems with any module connected to the bus. (airbag, radio, BCM, PCM, instrument cluster, heater control, and more) Find a shop that excels in these kinds of repairs (electronics/diagnostics) that has the Chrysler DRBIII scan tool and they can solve this efficiently for you.
