I changed power steering pump, alternator, and battery. Now NOTHING works, it will crank right up but no lights inside or out. Press the brakes no brake lights also. Also, won't shift out of park either. I don't know what to do. Please any help is greatly appreciated. I am new to this forum and I am trying to fix my mother in law's car. The alternator and battery are in perfect working order too. Sorry all the run on sentences and no grammar but I am in a hurry. Thank you for any help on this subject.
