...i thought i'd post my removal, cleaning, and reinstallation results using <A href="http://www.audiworld.com/tech/elec132.shtml">Kris' Tech Article</A>. My blower wasn't particularly unruly, just old. With my car approaching double digits i figured it couldn't hurt to free up some of the buildup in there and grease it up a bit, banking on some nastiness having accumulated over the years.

And, let there be gunk:

Thats all that came out of the motor after tapping it with a hammer and shaking it like nobody's business. I also blew into it with a compressor, which i would recommend, as it freed up a whole cloud of dust and other loveliness.

I simply removed the blower as instructed in the writeup, and squeezed off a little plastic piece to reveal this hole through which i later sprayed some electrical parts cleaner and some lube:

By the way, that little plastic piece sitting on the newspaper is the part i'm referring to that i popped off. After reinstallation it's been operating pretty much flawlessly, and i'd definately recommend cleaning it out if you have the time.

The brushes and commutator didn't need the spray cleaner and oil. Did you check the remaining brush length?

I didn't spray into the copper parts through the opening pictured, only on the back of the motor where the axis thing is. I have no idea what a commutator is, nor how to check the brush length. Looking at it and spinning it with my hand, everything seemed smooth and flush. Like i said, i wasn't having trouble with my motor, i only took it apart to clean it out.
