Change from single zone climate control to dual-zone

So this might be an off the wall question but I have a 2017 SR-5 Double Cab Tundra with single zone A/C unit. Can you upgrade to a dual-zone and besides the face place is there any other components that would need changed to allow this. I was looking at some schematics of a platinum and all the components appeared to be the same but I am assuming I am missing something. So if you could help it would be appreciated

 

WELCOME

 

Welcome. Aside from the controls, you'll need the dual blend doors and the ducting is probably different to accommodate the dual blend doors. IDK though. I haven't been behind the dash.

 

Hi,

Did you ever have any luck with this mod? I'm interested in doing the same. Thanks

 

Pretty much. A year ago I had some odd and VERY intermittent sensor issue with my truck; I've got the dual-zone auto HVAC thing.

I was asking if it was possible to 'downgrade' to the single zone manual HVAC system. I was told I "could" but they'd have to replace some other components particular to the dual-zone system (blend doors, actuators, etc.). It was prohibitively expensive UNLESS one either is a mechanic or already had/has it torn apart for something else.
