Sometimes the gas gauge works, and the temperature doesn't. Then sometimes the temperature gauge works, and the gas gauge doesn't and sometimes the clock numbers don't light up and sometimes it will display engine hot A/C off and cooling fans run on high.

This sounds like the PCM, or the instrument cluster is going bad, or you have a bad ground going to the PCM, we should run the codes to see if any are stored first.

This guide will help you:

If you get a code for the cluster here is how to change it out in the images below you can get a rebuilt cluster by searching google or Ebay. The same goes for the PCM. I have included how to change that out as well. Check out the images (below). Please upload pictures or videos in your response to the problem so we can see what's going on.
