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.
