Product review (1 stars): Defective on arrival!  DOA
I installed this motor and it immediately started making a loud, scraping sound.  Just to ensure the noise was not caused by something else, I disconnected the drive belt and the blower fan so only the motor was running. Same thing.

Others have commented they have experienced the same issue as I did, so perhaps there is a bad run of these motors.  The one I received was not in a factory box of any type.  Just a loose motor with a bit of foam around it.
