Dash Instrument Failure

[spen01ce]

We own a 2008 Newmar Mountain Aire. On several occasions all of the dash instruments fail (excluding air bag pressure indicators and fuel gage) for no reason. The may come back or not. We have a Spartan chassis. We have had to Cummins and Foretravel and neither have been able to diagnose the problem. Has anyone else had this problem. When we took to Foretravel it and the smart wheel were both inoperative ( this also included the windshield wipers and jake brake) and Murphy's Law the morning we were to take to Foretravel everything was working. Of course it is difficult to fix something that is working, thought they may have solved our problem by replacing a relay in driverside fuse and relay area outside, but on the way home everything except the steering wheel failed again. We are going nuts. Any help would be appreciated.

Yes, both Cummins and Foretravel (Spartan authorized service repair) have. It is stumping them also.

Although I have a 2001 DS gaser I had the same failure of dash cluster guages as well as the speedo & miles...
Bought the DS at Dallas & drove to Wichita Falls, was a bit nerve wrecking on our first drive...
Did my research & came to the conclusion that I would have to buy a new dash cluster...:(
One day I decided to unscrew the dash cover & take a peak at the back of the cluster...
To my surprise the harness connector had come unplugged, plugged back in & MAGIC, I had instruments again...
Can't understand how became unplugged as there are retainer snaps on the plug..??
I may put a dab of silicone on the connector before our next trip...
You can also clean the connector's contacts with a clean eraser...
