Sierra 2500 LE 6.6L

  • Automatic transmission
  • 298,500 miles

I’ve changed all of the ambient temperature sensors, vacuumed the system down then recharged it, also changed out the control panel! For some reason my ambient temperature is showing -50 when it’s 100 outside. I’ve seen where many people’s had the same issue without any answers on how to repair it. Hopefully someone can give answers to this issue.
