Per the service manual, it could be any of the below, which is why he really needs to have someone plug in a TechStream tool to narrow it down:

A/C Fuse
Refrigerant pressure
Compressor and pulley
Air conditioning pressure sensor
Evaporator temperature sensor
Air conditioning amplifier
ECM
CAN communication

Just hook it up and see what it says. Checked the stored DTCs first (which it will display as soon as you go into the AC section).
