The gearshift has a thumb button that requires you to press it before it will shift out of park. This is obviously a safety mechanism. There has been some of malfunction and the button won't go in. So I am stuck with a mustang that can't shift out of park. I already changed fuse #9, which is the fuse for this and also the hazard lights. The hazard lights don't work either.
How do I disable this interlock safety mechanism so I can move my car?
