Hi I recently purchased a 2005 Crossfire Convertible. The spoiler ascends out at the correct speed, but does not go down when I slow down. The red light flashes on the console. The spoiler will retract manually after I turn off the ignition and restart. Any ideas what this might be please.

 

Check your battery. It seems that the most common problem with the spoilers occur when the battery weakens. Is yours white or black? White is the original battery and regardless of any readings that you get, it should probably be replaced by now.

 

+1 on this, but you might also trying disconnecting your battery for about 20 minutes. This sort of re-boots the little computer "thingys" and straightens things out. Just sayin ......
