Thank you for the donation.
Between manual and auto HAVC, it is not a plug and use type of conversion.
The auto version has additional sensors that are not used on the manual version. For the conversion, wiring would have to be redone and additional sensors and controls and that would require exensive work unless you can get a complete wireharness assy with the relevant sensors.
For different year models, it would be even more difficult, especially with the newer models whereby body control modules are used.
I can't think of any other alternative if you can't get the correct parts to use and a wiring schematic would be required to understand the system.
