I received the second used BCM today and installed it. I now have all known to me functions controlled by the BCM except manual control of the rear wing. The wing goes up on its own at the speed that it should and retracts at the speed that it should. It just doesn't respond to the console switch. The console wing switch worked with the original BCM, but I truly haven't used it in over 8 months so it's possible that the switch has failed or a connector is loose. I will be hitting the schematics to check out the differences between manual control and automatic control.
Either way, I can live without manual control of the wing.
So, for now I'll just drive the Crossfire and enjoy it.
