I don't have an answer to this question, but I would suggest reposting the problem with a more descriptive subject line. I think you'll get more responses from others with the same problem if you let folks know what the problem is in the subject line. Try something like "Noisy blower motor, 2000 E320" or something similar. (A lot of listers may tend to see a subject like "noise" and just scroll over it.)

Good luck!
