The entire wiring harness on this car must be insulated with water soluable material....after wiggling and manipulating the rest of the underhood wiring things started working again....to get the turn signals to resume functioning I got mad and smacked the top of the fuse block under the hood....viola!!!! And the radiator fans apparently run until you enter the radio unlock code.....GENIUS those Germans are!!!! If I never see this car again, it will be too soon!!!
