My install went flawless when enabling Single Zone ATC and my steps below per M2mods:
**********
Include your
- Year/model/trim of truck/original fan speed>> 2014 1500 CC 5.7 with factory 8 spd
- Original radio/new radio model (& new pn) RA3 with dealer activated NAV. /// upgraded to RA4NA and 7" cluster
- 8.4 HVAC module PN (bought new or used?) factory module.
- Fan resistor you used (New OEM, Used OEM, or Clone?) N/A
- Conversion Harness: ie 4 or 7 speed w/Sgl Zone ATC support N/A
- Cabin Temp Sensor and/or humidity sensor (New or Used or Clone?) harness, sensors provided my M2Mods
- what you used to program: AlfaOBD PC or Android/OBDLink MX BT & steps you did (battery vs radio fuse pull between steps?) AlfaOBD Android with newest update
--> & what SW version of AlfaOBD you used!? newest v2.1.9.5
- Anything else that may be relevant >>>>
* I pulled BATTERY HOT cable before connecting harnesses and sensors
* Reconnected battery and verified HVAC , SirusXM and backup cam were GTG
* Did 1st AlfaOBD change to DUAL Zone.
* shut key off, pulled Afa from port and disconnected battery again
* waited just over an HOUR
* Connected battery and verified HVAC was now DUAL ATC when Sirus and cam looked good. all HVAC settings worked
* Did 2nd Alfa change to Single Zone. repeated, shut off, pulled alfa and disconnected battery for an hour
* reconnected battery, checked HVAC and all was GOOD. Manual / AUTO worked perfectly.
-- several drive cycles now and all is great. One of the BEST mods yet..
