Sounds like the compressor is seized (frozen). If it were just the bearings in the pulley the compressor would still work, all the time, even with the A/C off. HTH. -Jim

In my opinion compressor pully to be changed, sooner it will stop, if not changed now then it will effect battery and belt and more cost to you, may be you feel sound tik tik from engine.
