CSVIR - your symptoms describe a malfunctioning skreem module. It can only be diagnosed correctly with a DRB III scan tool that typically only authorized Chrysler dealerships have. There appears some threads that others have been able to do the R&R themselves most have had a dealership do the replacement. The skreem is VIN specific to you car. Search this forum for skeem module failures and then begin to look in your area for a dealership that has experience working on Crossfires and also has the DRM III diagnostic tool and a tech that knows how to use it.
