If the BCM was not programmed to your vehicle properly this can cause this type of fault here.The BCM needs replaced new when it is replaced as a used one will not program to your vehicle as it is already programmed and locked to another vehicle.Then when it is replaced a GM dealer or authorized GM service center has to program it with their computer.If it wasn't programmed this needs done.If it was programmed I would have a dealer check the programming in it to see if it is correct to see if it needs reprogrammed for a convertible model as it may have been programmed for a sedan with no convertible roof.
If this is found o.k. this may be a fault with the roof control switch as it may be seeing a signal that you are trying to close the roof when you are actually trying to open it.I have seen some of these fail before needing replaced.This would need to be checked into/tested further to be sure of the component at fault and repaired from there.
