You will get better results in a Chrysler/Dodge newsgroup, however I made the same mistake buying one of these lemon vans. There is a serial bus between the engine computer and the body computer/dash which carry the data for the gauges. Its common for a pair of transistors to burn out that drive this bus are prone to burning out. If you can solder its an easy cheap fix. If not then you either buy parts from a junk yard or pay the big $ to a parts swapper.
