Have you tried manually retracting it? There is a toggle switch on a panel just forward of the driver door inside the passenger compartment near the clutch pedal for manually extending and retracting the spoiler. If it doesn't move when the switch has been pushed I'd check for a blown fuse then a bad relay. If it does retract and extend using the switch (make sure it does both) then the problem probably lies in the automatic switch.
