Well an unexpected ice day, called school off, so I didn't have to die trying to get to school to teach. So I worked on the fan today and I believe it was successful.

Now, I just got done and we'll see how long it lasts, but I'm hopeful that by a good cleaning and lubricating the bearings and shaft, I should have a quiet motor for sometime to come. It beats buying a new. However, this is of a P.T.IA. to get at those small torx screws in the back where the motor is bolted to its mount.

UPDATE - When I was reassembling the blower housing, I noticed that there was a "arm" that controlled the driver side flap that was disconnected. This was the fresh air blender, which now works, I now have warm air for my feet, hands and upper vents. Prior to this, I was just get cold outside air. So, this was a very successful day.
