This is an amazing amount of useful information. I am really hoping this is what my issues are. Coming out of -23 degrees C weather, and I have no blower fan. Going to to try this out, and keep my fingers crossed. Thanks WindTrackMind!
This answer is late , but for the record.. 07-09 had the problem with the brushes design/material ground off till there is poor or no contact with rotor. When treated immediately as posted with lubricant to reduce drag they get extra life but eventually will fail, usually in winter when you need it most. Replacement is easy as described and they are on E-Bay for around $50.00.
