I would like to know if someone has the diagram or know how to remove the heater blower unit from an ES350 2008, i need to clean out the unit since i can hear rattling when the blower is on, sound like foreight objects inside.

thank you in advance instead getting the dealer to clean it out for me.

I google a little bit and found this: http://lexus.sewellparts.com/images/...000/878376.jpg
