Rear spoiler stuck in upright position
 

Hello,
I have an issue with my Mini Cooper Convertible (2014 plate)
The rear spoiler is now stuck in the upright position,up until yesterday I was able to close the spoiler but still have the alarm constantly bleeping,as of this morning I can't close the spoiler (I can still hear the spoiler mechanism attempting to close as soon as I switch on the engine.
I have lubricated the spoiler and the weather has not been cold lately.
I initially thought that it might have been a blown fuse but my local garage says it may be electrical.
Since the spoiler was closing up until recently could it just be a loose wire or is the spoiler motor mechanism faulty?
Any help would be grately appreciated.
