2014 Sierra WT A/C Cluster Swap

[James Buchanan]

Hey everyone, I have a 2014 GMC Sierra WT Crew that I am doing some major upgrades to. I have been reading the forums about people wanting to swap the base single zone controls to dual zone even tho these trucks dont support dual zones. I have been reading and came across that the Colorado/Canyon are single zone and have a nice looking digital readout. So I bought one! Everything seems to be working but when you turn off the system the temp and fan speed do not go off. Actually the fan speed does not adjust at all. Has anyone tried to do this mod yet or am I the first? It looks good to me tho. Better than non operational second zone.

After it being in for a few hours, Im having the same problem that the dual zone does where it wont turn the fan motor back on without unplugging it. Temp dial still works but no blower.

Unless you update the HMI (not sure about BCM), it's going to be a difficult swap, IMO.
