My 98 grand caravan (3.3L/flex fuel) is puzzling my mechanic and me. On a fairly regular basis the gauges stop working. but usually after a few days it will start working on its own. It does throw some codes, no signal from the CCD bus, no signal from the TCM, no signal from the BCM. Here is what is and what is not working;
-Not Working- temperature gauge tachometer speedometer fuel gauge [on overhead console]; all info except outside temperature and compass. (the lights do come on but do not show info) odometer, shift indicator
-Working- odometer has been keeping track when it comes back on all the driver information above the gauges. all other electrical.
The engine and transmission seems to be running the same as usual.
any ideas would be welcome. thanks
