    Horrible sound, A/C Tensioner Pulley needs to be replaced. A/C still works, as does heater. But it is about to go out (causes a grinding sound in front left engine area, that changes pitch when you hit A/C switch or heater switch)

    This problem occurred after a catalytic converter replacement. The first shop said that this would run me $385 to replace the Drivebelt tensioner as well. Luckily, I had another shop replace the pulley for $90 and it did the trick.
