Problem with A/C blower motor
 For those new owners of a BMW X5 3.0si, there are several units with a problem with the A/C blower motor. If you have heard a grinding noise coming from the inside of the A/C vents, you have it! The part is in back order. If you haven't heard the noise, contact your dealer and ask if your car has the problem.  Pray that your dealer is honest and will tell you the truth. Very, very frustrated with the brand. A $60K should be flawless.
