QuestionA little while back my sienna started squealing when I started it with the AC on, and if I turned the AC off, the squealing stopped. I told myself I would get it fixed soon. Then, a couple of days ago, I started the car, and the battery light went on, and the AC stopped working (only blew warm air). Also, I no longer hear the squealing. Today, it wouldn't start. I jumped it, drove 100 yards and it died again. Serpentine belt? Alternator? I appreciate any advice.
AnswerSounds like either your A/C compressor is broken and damaged the drive belt (which drives other components)
or
The serpentine belt could have failed by itself and now nothing is being driven i.e. alternator, A/C, power steering, etc. Since the alternator is not powering the car, your battery is not being recharged. It has been drained.
