So I have a 2011 Impala, The DIC displays the temperature as "_ _ _". I hook up a scanner and found that OBDII scanner could see what I believe are all the temperatures. However My DIC shows nothing for I guess would be the outside temperature.
Does anybody have any experiences that might offer some guidance on how to figure this out?

This happened to me when I replaced the HVAC control unit. I had to have the control unit reprogrammed. Since I don't have a Tech2, a trip to the Stealership was required.

Thanks for the reply. I was thinking there might be a problem with my BCM. I am going to hold off on going to the Dealer for a reprogram.

I might explore buying a preprogramed HVAC module if possible.
