I have a 2000 GMC Sierra 1500 5.3 reg cab short bed 4wd. I've been having gauge problems with this for the last month. Nothing on the gauge cluster works besides (oil pressure, voltage, and turn signals) my message center does not work or Rpm gauge or speedo nor my toe haul or high beem light on the gauge cluster. I've Tryed a different gauge cluster and I still am not sure. If any one might have any suggestions that would be awesome! Thank you!
