The wiring I should have little problem I have All data so I should be able to get the wiring diagrams. The blower doors I could just replace the entire case to a climate control case. Am I correct or am I missing something major. Is there another body control computer for it that I also need to add or change?
Thanks John
I believe you would have to swap out the whole heater core/evaporator housing assembly which woud be a nightmare to include getting all the wiring properly hooked up. Even if you had a GM service manual it would be difficult because of the errors and inaccuracies in the documentation. The dual zones have two temperature actuators not just one like the basic HVAC unit. Also, the digital dual zone uses an ambient temperature sensor which would have to be wired in. You will need a blower control module and new blower motor to include wiring. The digital does not use a blower motor resistor.

I recall the advice we gave to the last person that wanted to do this was forget about it. But if you put your mind to it, have time, access to parts and the funds available to do it then nothing is impossible.
