Car died on the highway. Alternator went out, but before it went out the gauges quit working and the AC stopped blowing very hard. Replaced the alternator. The battery still needs replaced. Now the gauges still arent working. The illumination and blinkers work but nothing else. Also when the car comes to a stop the radio shuts off until you give the car gas again as if it wasnt getting power and AC blows slower and hotter. Not sure if this is all from one thing or individual issues. Checked all fuses and all are good. MOstly concerned about the gauges because the fuel and temp gauges are stuck where they were and we have no rpm or speed. HELP!
