This video shows how to remove the blower motor and fan assembly for the ventilation system on a 2005 Scion tC. It's located behind the glove box.
This will help you if you need to replace the blower motor and/or fan or just clean debris out if it. In my case I only needed to clean debris out of it to fix the noise it was making.
This likely applies to all Scion's and other makes and models in general, however the process of removing the unit in other models likely varies.
How to change your cabin air filter on the tC or add one if it doesn't have one is also discussed.
