Thanks for the update. That fall code is directly related to your AC compressor clutch problem. The ground comes from and through the ECM and controllers. The controllers will connect ground through its inputs and outputs even for fan functions as well taking the place of a relay in the circuit in a lot of cases.

Resistance Test: Perform an A/C clutch coil resistance test with an Ohmmeter. Typically, a clutch coil should be between 2 and 5 Ohms, and any reading below 2 Ohms or over 5 Ohms indicates a bad coil. A reading of 0.00 indicates that there is a shortage in the windings. A reading of O.L. or infinity indicates an opening in the windings.

You can check the fuse of your car's AC compressor if it is working or not by using a multimeter. Turn the engine off first before removing the fuse for the AC compressor. Check if both ends are still electrically connected with a multimeter or other devices.
