Since the CLC LED comes on the CLC software is running. With a bad power supply you don’t get the watchdog. Can you talk to the selector and door with everything plugged in? If you can, replace the CLC, if you can’t, make sure you have at least a meg ohm from PSC to ground and from NSC to ground on the harness without comm plugged in on all 3 cards. Also try removing the “trans orbs” that go from PSC to ground and NSC to ground. Comm will work without them but they will take down comm when they fail. If that’s the problem you can let the car run but do replace them.
