One member did it. LOTS of work, expense, and GM insider knowledge needed. Everyone else is persuaded to not do it after reading his report. It's not a simple plug and play due to the addition of 8-10 additional sensors in various locations around the ductwork and cabin.

Yes it can be done you need a blower motor controller and wiring back to controller upper and lower air temp sensors left and right and all wiring you also need an interior temp sensor and wiring an ambient temp sensor and wiring sunload sensor and wiring wiring from controller to bcm a dealer that will flash the bcm a couple of weeks of spare time and alot of beer and patience did I mention u need lots and lots of new wiring?
