I loose my tach, speedometer, oil pressure, coolant. My lights come on for service 4wd, battery light, abs, check engine, brake control module and it goes crazy. I unhook all my battery cables for couple of hours and hook back up use my CTS clear codes and it works perfectly for a month or so and same thing happens. Any suggestions?

 

you would need to get the codes read to determine a starting point. sounds like a module losing communication.

What year and model is your Ram? Have you recorded the diagnostic codes before disconnecting the battery and using the code reader or scan tool to clear them? If so, what codes are present? Does the truck continue to start and drive even when everything is wonky? Does the issue seem to be primarily limited to the instrument cluster?
