Hi! First off- many thanks for all the info available on this forum provided by BMW enthusiasts. I have been able to work on my car with more confidence because others "have been there before". This post is to address the frequent complaint of the blower fan misbehaving. I took the shortcut and followed the most frequent advise to replaced the FSR and it worked so far! The old part did not look old or different from the replacement, no visible sign of heat damage, but obviously was toast. Hope it will work for you as well.
