Unplugging the AC controls had no effect. When I had the motor out I tried to use a screw driver to turn the shaft on the shift motor, it was locked up solid. Should I be able to move that manually?

I doubt all scanners can read the 4WD module, and only high end scanners can control the 4WD module. FORScan can likely read the 4WD module with right adapter.
I'm not sure if you'd be able to turn the shift motor with a screw driver. I never tried. I wish I had kept 1 of the old ones I had so I could take it apart.
I am a big fan of testing to the point of positively identifying a failure before spending money, but in this case it does seem like it's the shift motor.
