HVAC Fan

If you do not have a cabin air filter installed the hum may be due to something having been sucked into the fan (like a piece of paper from the glovebox).

Hi Scott.. I had a cabin filter front new.. I did find a another thread and it was noted that toyota changed the part# of the blower around 2010/09 , so I am going to assume they revised the blower motor and maybe to address it being a bit noise.

Interesting - I just looked in the EPC and there are 2 different part numbers. 87103-52140 and 52141. I have 52140 on my 07 and 08 and 52141 on my 09. I don't hear a difference between them. The part number is on the center of the bottom of the blower motor.
