2007 WRX wipers going crazy!!!

I have a 2007 WRX. When the car is on, the wipers will come on when not selected. The column wiper switch position doesn't impact what the wipers do. When the car is off, but in the accessory only mode, the wipers will do what the wiper switch selects. The wiper switch has been replaced, The wiper motor has been replaced. No change in the wipers being possessed. Help!!!
