I mentioned this problem on another thread yesterday, but after taking my truck in for service I need more info. Over the weekend I was driving home from Kansas and several times the instrument panel went blank. Not just the DIC but the gear display and clock also. It came back on each time, but not always the same way. ie, once just the gear shift display came back on and then a few minutes later all displays returned. Sometimes everything went off for up to 20 minutes. By the time we got home everything was normal. Bob took it in for a driveshaft replacement today and told the service advisor of this new problem. All they did was turn up the dimmer switch and commented that there was no problem. I know what my instrument console should look like and the display was off, not just dimmed. I didn't have the dimmer off and the displays went blank on their own and came back on by themselves. Does anyone know what has caused this. I'm sure it will happen again and when I take it in this time I want it fixed. They didn't even listen the symptoms or they would have known it wasn't just the dimmer switch turned down.

Thanks in advance for your help. This is really confusing
