how do i fix my power windows and ac and air bag light

For all these systems to suddenly act up I would expect a main fuse or a control module failing which would require a scan tool capable of reading Chrysler Body Control capabilities. Have you looked at the fuse chart to see if all these circuits share a common fuse or power supply. Your owner's manual may have a fuse chart.
