When I am driving with the Air on full. The radio and my gusges go out. As soon as I turn the air off they come back. The car never dies. About a week after this happpened I started the car and turned off the car. Went back 2 minutes later the battery was dead. The battery is 4 months old. I had a mechanic check the starter, altenator and battery. They said it was fine. However he didn't check it when the air was on? Could it still be the altenator or possibly the belt?

Hi Jfeliccia,

Do a load charge test and measure the voltage at alternator and battery.

It could be the belt, but that should be squealing most of the time. The other thing I would suspect is a faulty crank pulley.
