Hello house, I drive a 2000 Camry and recently noticed that when I am in serious stand still traffic with AC on ,my battery lights come on,but if I put off the ac the battery light will go off. Also, I realise that my rpm is way below 1,before it was just a little below 1. Then secondly I get a sound that makes it look like the engine is working very hard. In the morning, the battery is dead and can't Start the engine.

Also,if the road is free,the light does not come in at all and battery remains sound.

Please what could be the cause and possible solution .

Check fan belt. Check alternator

Check charging system comprising of your power source and alternator, also check your drive belt as well. As for your Rpm going so low did ypu recently have your compressor changed or kazeem worked something else for the car?

no Kazeem did not work on it. The major thing I have noticed is that above 1rpm its good. Below that, the light comes on.

Check your serpentine belt
