Default Long list of dtc codes need help

My dad has a 2001 C-5 with alot of codes i have replaced the ignition switch and the battery. I'm a decent mechanic I have a small repair shop of my own but i know when to ask a pro. It all started with the guages starting to fail and progressed to total shut down of the car. i replaced the battery and disassembelled the ignition swith and cleaned the contacts that fixed it for while untill I replaced the ignition switch later and the problems seem to be coming back. In the mean time I have purchesed the HP-Tuners Software to tune the VCM. After scanning for the first time i saved the DTC log and noticed a lot of class 2 com fail to multipull moduals. cleared the codes and sent him home. later I installed a Cold air intake kit to the front vents and saved a second DTC log some of the same codes but not all reterned. CAN ANYONE HELP

P.S. I have attached those DTC logs
passenger side door has no controls
