So I opened my hood this evening to find that the three power cables connecting the compressor motor to the controller were completely twisted up. Upon further inspection I found that the DC motor and the plate to which it is attached are able to move with respect for the compressor housing. The large retaining ring is still in place; however it appears to be able to move independent of the plate too. I can turn the DC motor fairly easily with my hand in both directions.
EDIT: I have removed the compressor and reverted back to stock until I can get this sorted out.
This is a video of me rotating the motor and plate. You can also see the retaining ring move.
