It's possible that it's an ignition switch problem.... but, odds don't favor that... I would say that it would be more likely a starter solenoid problem... which basically means you'd need a new starter. The problem could also be a loose electrical connection to the starter. I'd recommend checking and cleaning the connections down on the starter before buying anything. However, my money would be bet on it being a new starter you need.
REPLACE BATTERY CABLES.SOUND LIKE POOR GROUND AT BATTERY GROUND CABLE.IF BATTERY CABLES OLD AS VECHICLE REPLACE THEM.TURN OFF RADIO FIRST BEFORE REMOVING BATTERY CABLES.IF BATTERY CABLES OKAY.THE STARTER MOTOR COULD BE GOING BAD.
Sounds more like the Alternator or Voltage regulator is not charging the battery correctly. Have the Alternator checked. If you remove it and take it to Auto Zone or Advance Auto they should be able to test it for you.
It sounds like you have loose belt(s). When the A/C is turned on, it puts a big load on the belt, if it is loose and starts slipping and squeeling, then the alternator won't turn, so the battery runs down as you drive. Make sure all your belts and battery terminals are tight.
alternators come in different amperage rating. connect a good ammeter in series with battery positive terminal after engine is at idle. or connect a voltmeter on your battery. with engine at idle, turn on lights and a/c, raise idle at between 1500 to 1800 rpm. voltage reading should be 13-14 volts. if not, alternator is too small. check the amperage rating of your original alternator. good luck
when your car is running disconnect the positive cord from the battery. if the car stays on, than it is your alternator, if not its your battery. also if the car stays on, the head lights go dim if the alternator is malfunctioning
