Just to jump in the volt meter on this cluster is just displaying the voltage that it gets on the ignition 1 feed which is pin B6. Can you turn the ignition off and back probe this wire and see if you are getting any voltage on it? You should have 0 volts when the key is off.
As Joe mentioned before, if you have an issue with the fuel and trans temp gauge as well then those are what are called Class 2 bus messages. This means this is a coded message from the PCM to the cluster and the cluster displays the message after it decodes it.
So if you are getting these gauges fluttering when the ignition is off then we have something backfeeding through the cluster or voltage from another place.
Also, on a completely different path, we need to load test the battery.
If the voltage is low, it causes erratic action and I just dealt with a different vehicle where the gauges were flickering and it was a battery issue. It didn't match this exactly but it is something that we need to check.

Just make sure we load check the battery and not just put a meter across it. Parts stores will do this for free.
Lastly I just want to state that the gauges flickering is going to be a different issue then them not working. However, if you have some codes for the gauges then that could change.

Let us know what you find with this voltage and then if the battery passes and finally if you have any codes. Thanks
