So, I'm stoked to find other people with this problem. I own a 2000 Xterra (seems related to 2000 models??) and it is having the exact same issue where the instrument cluster completely shuts off periodically. This includes the odometer which is frustrating because I no longer know the true millage of this car. Its been doing that since we purchased it a couple years ago. who knows how long its been doing this!
One thing I noticed was the cluster shuts off when the engine is Hot. So, either a long drive tends to set it off or when my thermostat is having issues. This car has had MANY issues, but this one seems steady and is getting worse.
Anybody know if there is a relation to the temperature??? Loose connection??
