BCM setting for auto cabin temp

[Joe Merchak]

Hey Guys

I have a 2018 Ram 1500 Express and I upgraded my radio to the 8.4 4C NAV UAQ radio because I wanted android auto. I had the RA2 with 7 speed control. The bezel that came with the kit has the auto temp option which when I first turn on was on the radio but the BCM took the function away. Does anyone know if I can use alphodbii to turn the option back on? If so do you know where it is?

I have done changes but only the ones documented because I have listed to the warning and not experimented on my own.

Thank for your help

Joe

Yes but you need to add a few parts, you'll need to add the cabin temperature sensor (driver's kick panel). and the a humidity sensor(by the rearview mirror).
There's a whole thread on the subject: https://www.ramforum.com/threads/ho...to-a-manual-temperature-control-truck.103456/
You'll want to order the additional wiring harnesses from: M² Mods
and the sensors from: AllMoparParts.com
There is even instructions in the first post of the AlfaOBD thread.
If your bezel has two sets Warmer/Cooler adjustments, only the left ones will work.

Just FYI, that auto option will reappear every time you disconnect power from the radio. It disappears once the radio reads the proper configuration for its currently installed vehicle.
