Check the fuse in the end of the car charger. The tips usually unscrews, and in some cases you will have to take it apart to get at the fuse. If the fuse is still good then most likely the wire is broken or the soldering has let go at the end that plugs into the cars power plug. Replacements are sold at most locations that sell these units or if you are really stuck, try one of the major truck stops, these are a common wear out device for truck drivers.
