I have a 1999 Dodge Grand Caravan and have an electrical/computer problem. First the ABS light comes on, next the Security light, then I loose all gauge functions, and AC/heating controls, then Chech engine light comes on. Van runns Ok, Two hours at the dealer found nothing, reset the Check Engine and sent me on my way. 15 miles later same thing happened again. Any recommendations? Dealer says he can start changing parts until it corrects, but nothing comes up in the when they run their computer tests.
