How To: Install a 2018 4C (UAQ/UAS) Radio in 2013 - 2017 RAM

[snipermaven]

Hello everyone I have a 2013 Ram 2500 that came factory with the 8.4 vp4 radio with dual climate control and heated/vented seats . I upgraded to a UAS radio got the conversion harness from infotainment to get the heated/vented seats to work I also upgraded the hvac module to P/N 68366553AA and I still don’t have full control of my climate controls. I’ll be on the lowest ac setting and when I press the hot button once it jumps to hi it will not display the temperature just says hi or low. Does anyone know of a fix for this. I also have a video of the issue as well.

I have this same problem. I installed the UAS and harnesses and everything works except the temperature. I only have HI and LO. Mine is a 2013 Ram 2500 Longhorn. Dual ATC with 7 speed fan. I also upgraded the HVAC module and it did not help.

I’m at a loss.
