So the little battery icon has appeared on my dash and my aircon shuts down every time it appears with in 2 min of starting my car. The manual says loose serpentine belt, battery needs changing or dirty terminals. I have changes the battery, changed the belt and cleaned the terminals. The icon continues to show up and shut off my aircon. The odb scan shows no errors. I tested the volts the alternator and it was putting out 13.2 volts. Which I thought was a bit low. So I put a brand new alternator on it. Now it charges at 14 volts. How ever the fu#&ing fault icon still appears on my dash 2 min after starting the car and continues to shut down my aircon. It's been consistently over 30 degrees every day for the last 2 weeks and I'm seriously over not having aircon. Any help would be greatly appreciated.
