Hi Wallyx5,

Replace blower and put back everything are fine but when I turn the heater/ac to high or defrost, it make loud noise, like vibrate noise from the blower motor fan. The part is #64118385558, bmw dealer give me the part #. Please let me know what to do next. If I turn to about 4-5 knot, it fine.

P.S. take me and friend of mine approximately 4 hours to remove and put it back.

Thanks,
Henry
