Single Zone ATC upgrade problem 2016 Ram 1500

youtu.be

So I had the problem after upgrading to 8.4 UAQ where the AC blows hot air and would only work on the MAX setting so I got the harness and cabin temp and humidity sensors to fix it. Installed those and made the change to single zone MTC using AlfaODB. After a day or so the AUTO option appeared on the screen but it will only let me select all the way to HI or LO and with LO selected the a/c blows hot air?

Any suggestions?

It's been 14 mos since you got the ATC HW from me.... has it worked correctly until now?

I will reach out by text tomorrow and see what's up.
