I upgraded to 8" uconnect radio awhile ago,, I just finally got around to switching out the 4sp bezel to the 7sp fan control,, I had the harness made, i installed the new ac module,,,
Currently the temperature controls don't work or the volume controls,, only the hazards button,, is there something I need to activate with alphaobd,, I thought it was just plug and play at this point,, maybe a bad control panel?? ,, I can adjust fan speed on radio and climate controls just not with the physical buttons, any ideas that would be great,, thanks
