I seem to be having trouble with my climate controls after upgrading to a UAQ in my 2013 1500. When adjusting the temperature, the radio does not accurately display what is coming from the vents. For example, it will show full hot, but cool air will still be coming out of the vents. I need to press the heat button about 5-10 more times to actually get to heat. Another thing that may be notable is that the radio displays the outside temp in celsius with no option to change units in the settings where it should be.

After reading the following posts about similar issues it seems like the common fix has been upgrading to ATC which I have just completed following the M2 Mods harness and instructions on here with alfa OBD. Change to Dual Zone ATC, wait for radio reset, then Single Zone ATC.

I now have Single Zone ATC configured for my truck and the issue still persists. I made sure to pull the inline fuse between changes to reset the radio. The climate controls seem to work properly and display the outside temp in fahrenheit until the full configuration is set on the radio. I will link a video showing what is currently happening along with other relevant information.

I have been looking through many threads but I cannot seem to find an answer to this. Any help would be appreciated.

Thank you,
