Problem with 95 GP
 

My fiance was driving to work this morning in her 95 GP. She was driving along around 30 mph when the tach and speedometer just quite on her. Also, when you put the car in gear the locks do not automatically lock, and when you kill it they don't unlock. If you use the remote or the auto lock button, they work fine. I checked all fuses in car and under hood, and nothing was wrong there. Any ideas on what to look for, or what this could be. TIA
