So i just replaced my serpantine belt not too long ago and everything was running great until this weekend. I started hearing squealing noises from the belt again and now whenever I turn on the AC & press the snowflake button to make it cold the engine starts to vibrate a lot and the air doesn't get cold. It's not to the point it will not drive but there's noticeably something wrong. Also with this I am getting notifications to service my battery charging system from time to time. I thought it may be a pulley that's off at first but now i fear it's the compressor. I've had the car 10 years and have never had any issues with the AC.
