I noticed today that my fans in the dash was making a slight high pitch squeel when on the low setting. Anyone ever experience this? Did you work with the dealer to resolve? I am guessing a bearing issue or perhaps it is loose. Not sure if this is covered under the extended warrenty. Thanks.

My fan -on the low speed setting - makes more a low pitch warble than squeal. I ignore it as my warranties went by the wayside long ago. Ask your dealer if it is covered.

Your symptoms are consistent with a dry bearing. You have a pressed on squirrel cage blowere wheel. It won't come off and can't make any noise. It's the motor front bearing which is making the noise. They cannot be oiled so the motor will have to be oiled. Amazingly, it is not a horrendous job and can even be done by a good do-it-yourselfer. The motor and blower wheel come fastened together as a unit I believe, but do check with Orient or a parts house to confirm it is not available separately.

Blower motor whine is a common issue with the e9x. Replacement is fairly affordable, as DSX mentioned. I had mine done by Turner with a "used" part from a car being stripped for race conversion. Cost was less than $200. :)

Mine does the same thing. It's only in the 2-3 bars fan speed. If I either lower to 1 bar or increase to more than 3, the sound disappears. I am not under warranty anymore and chose to ignore it. If it's only $200 to fix I may want to do it, but my fear is that any time something is replaced it introduces a possibility of other things failing. I know this does not sound scientific, but it's been my experience. My buddy also told me to ignore small things in a BMW, since fixing them (even under warranty) may introduce bigger problems later.

I am somewhat glad that it's not just my car doing that. Misery loves company.

You don't have to pull the dash apart. The blower is fitted behind and below the glovebox and access is gained by removing the trim panel above the passenger's feet. Usually just four or five screws hold the blower in the housing and no part of the housing need be disassembled to remove it.
Changing the blower assembly should not affect any other component in any way, it's a self contained stand alone unit.
