My daughter has a 2002 Neon ES. I was trouble shooting a blown acc. fuse and fixed it. She got in to drive the car and all these weird problems came up. The biggest being that it won't shift. It's an automatic. Also the engine light stays on and the speedometer won't go up. Did I blow out something else? PLEASE HELP.....ANYONE?????
