I just bought a 2004 Crossfire 2D CPE from my father. I need some recommendations for where to take it for maintenance in the Tulsa area. Most of the dashboard lights are stuck on and the speedometer and odometer are not working as well as the back fin is stuck in the up position with the light flashing on the control button. My father told me that all that happened when he changed out a dead battery. The Chrysler dealer and mechanics have no clue. All fuses and most connections have been checked. I suspect I need to take it to some Mercedes maintenance location instead of a Chrysler one. Please help. Thanks.
