Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

Your battery light is controlled by the duty cycle to the alternator from the PCM (computer) and when it comes on it simply means the alternator is not charging and its not usually due to a battery concern. The fact that is not charging may be why the AC is not coming on. You stated your mechanic hooked up to computer and got a list of problem. In most cases when the PCM sees a charging system fault it will set a fault code. Do you have the fault codes he retrieved when he ran the scan? Post back with them and I will see if I can help you with this concern.

do not have any codes. said about 10 showed up recommends electrical system check up

Well then his next step would be to check the charging system when the battery light is coming on. In most cases this usually means the alternator is failing.
