I have a 04 Saturn Ion with auto transmission. When I go to shut off the ign. sw. after driving the ign. key won't shut all the way off and you can not remove the key. The key operates just fine. I can start the car, turn the engine off but the key won't turn all the way off to release the key. I was wondering if it could have something to do with the neutral safety switch on the transmission. Does anybody know how I can access it and test it to see if that is the problem? Thank you.
