My display in the instrument panel that shows the DIC and the gear selection (PRNDL) randomly goes off for a while and then comes back on later. Pressing any of the DIC buttons does nothing. It is not an illumination issue as the rest of the gauges stay lit. Sometimes it will go off and on while I am driving. Sometimes it will stay off until the next time the car is turned off and on again. Sometimes it will stay off for a few days. Is there anything simple to check for this like a fuse? I can't imagine what could cause it to go off and on so sporadically.
