I have a 1997 Grand Caravan SE with a PCM fault code. All gauges stop working. We have just tried a new(used) computer, and a day later all the gauges went dead again. The place we bought the computer from is sending another, just wondering if something else is to blame. If we restart van, all will reset and work, just not for too long. Any comments???

 

next time the guages fail, unhook the battery for at least 30 seconds.... let me know if that works
