Climate Control shut off either while driving or at start up. Did scan and got this code (B1726 Display Control Unit Lost Communication with Climate Control Unit)

Any ideas
Thanks.

 

From what I'm reading, "B" codes are all electrical. The obvious answer seems to be that the display/control unit from your AC isn't sending a signal for your AC to actually work. Check fuses, and of course unplug negative on battery for a minute to clear everything and see if it comes back.

Have you modded anything that required you to go behind the radio? maybe you didn't click the HVAC control plug in completely and over time it got unplugged?

 

It's Intermittent Problem. Sometimes works fine other times, it won't start for 20-30 minutes.
I will unplug the Battery.
Only mod I have is HID fogs with a relay.

 

Still acting up,
