Thanks for you great DIY instructions. Here is my experience with this for all those who have a weak blower.
Symptoms: fan workes intermittantly and very slowly when it did, could get it to move by banging near the glove compartment area (like the Fonze)
Removal: much easier than changing the cv joints on my car, less messy and the actual blower is plastic so its not to heavy when installing/removing. 10mm socket, 8mm socket and phillips screw driver is all you need.
What I found: Yes, twigs, leaves and feathers in the cabin filter... I wish they installed a filter upstream to the blower so all that stuff would not get into such a hard to get place.
I opened up the blower and removed the motor. Motor was jam packed with carbon residue, since there are no open breathing holes for the motor. I cleaned all that out. I also noticed that after 150k miles and 12 year that there was only about 5mm left of the motor brushes, i could start seeing the spring on one brush ( brushes did not look like anything special, you should be able to find them somewhere). I put some grease on shaft and put it back together.
Result: Blower works just like it did 5 years ago just fine
Lessons: before buying a whole new blower, consider just taking a look at the motor and cleaning out the carbon and checking the brushes.

Thanks
