Default Cooling and heating help

I'm looking for help with my 99 grand Cherokee limited 4.7. I ran the AZC test and pulled four codes.

46-AI (recirc) motor was not responding

52-AI (recirc) door travel range too large

54-Left temperature door travel too large.

56-Right temperature door travel too large

My question is what parts do I need to buy to fix everything and where should I start.I recently replaced my heater core so it sucks I didn't run codes first. Can I fix the #46 fault code without taking the dash off again? And is it possible fixing #46 fault would fix the rest of the faults? Im assuming 52,54,56 are blend door problems and 46 is what opens and closes doors. The blend doors looked in good shape when I was inside for heater core so I'm hoping 46 fixes everything. I'm new and learning as I go so I could be completely wrong. Any help would be much appreciated.
