I went to go to work this morning and the car wouldn't start. Tried to turn over but didn't have enough juice. I gave it a jump start and it started right up. It ran ok but nothing else was working. No radio, no air controls (heat, AC), no blinkers, no headlights, no interior lights, no power windows, no power door locks. The temp, fuel level and oil pressure guages weren't working either. The only thing working was the Speedometer and the tach. Anybody got any ideas about what it could be or where I should start looking first.
